SYNONYMS C2-O4.2Na, "ethanedioic acid, disodium salt", "oxalic acid, disodium salt" Section 2 - HAZARDS IDENTIFICATION CANADIAN WHMIS SYMBOLS EMERGENCY OVERVIEW RISK Irritating to skin. Risk of serious damage to eyes. Harmful in contact with skin and if swallowed. POTENTIAL HEALTH EFFECTS 1 of 12 Sodium oxalate sc-203396 Material Safety Data Sheet Hazard Alert Code Key: EXTREME HIGH MODERATE LOW ACUTE HEALTH EFFECTS SWALLOWED ! Accidental ingestion of the material may be harmful; animal experiments indicate that ingestion of less than 150 gram may be fatal or may produce serious damage to the health of the individual. ! Soluble or solubilized oxalates act as severe corrosive agents within the alimentary tract and may be lethal as a result of severe gastroenteritis and secondary shock. Where gastrointestinal symptoms are absent (as is the case with dilute solutions) systemic effects may dominate resulting in muscle twitching, cramps, depression of respiratory and cardiac functions. Other symptoms of poisoning include vomiting (often bloody with coffee spots), pain, weak and irregular pulse, headache, stiffness, convulsions, stupor and coma. Kidney damage occurs, causing a reduction in frequency of urination, and also protein and blood in the urine. EYE ! If applied to the eyes, this material causes severe eye damage. SKIN ! Skin contact with the material may be harmful; systemic effects may resultfollowing absorption. ! The material may cause mild but significant inflammation of the skin either following direct contact or after a delay of some time. Repeated exposure can cause contact dermatitis which is characterized by redness, swelling and blistering. ! Oxalate ion is an irritant and may cause dermatitis. Following contact skin lesions may develop. Epithelial cracking and slow-healing ulceration may follow.They fingers may appears cyanotic. ! Open cuts, abraded or irritated skin should not be exposed to this material. ! Entry into the blood-stream, through, for example, cuts, abrasions or lesions, may produce systemic injury with harmful effects. Examine the skin prior to the use of the material and ensure that any external damage is suitably protected. INHALED ! Inhalation of dusts, generated by the material during the course of normal handling, may be damaging to the health of the individual. ! There is some evidence to suggest that the material can cause respiratory irritation in some persons. The body's response to such irritation can cause further lung damage. ! Persons with impaired respiratory function, airway diseases and conditions such as emphysema or chronic bronchitis, may incur further disability if excessive concentrations of particulate are inhaled. ! Inhalation of soluble oxalates produces irritation of the respiratory tract. Systemic effects may include protein in the urine (albuminuria), ulceration of the mucous membranes, headaches, nervousness, cough, vomiting, emaciation, back pain (due to kidney injury) and weakness. Inhalation of soluble oxalates over a long period of time might result in weight loss and respiratory tract inflammation. CHRONIC HEALTH EFFECTS ! Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or biochemical systems. Exposure to the material may cause concerns for human fertility, on the basis that similar materials provide some evidence of impaired fertility in the absence of toxic effects, or evidence of impaired fertility occurring at around the same dose levels as other toxic effects, but which are not a secondary non-specific consequence of other toxic effects. Long term exposure to high dust concentrations may cause changes in lung function i.e. pneumoconiosis; caused by particles less than 0.5 micron penetrating and remaining in the lung. Prime symptom is breathlessness; lung shadows show on X-ray. Chronic exposure to oxalates may result in circulatory failure or nervous system irregularities may follow prolonged calcium metabolism due to oxalation. Prolonged and severe exposure can cause chronic cough, albuminuria, vomiting, pain in the back and gradual emaciation and weakness. Prolonged or repeated overexposure may result in delayed liver and/or kidney damage. Certain rare individuals are subject to oxalosis (deposition of oxalates in the kidneys) and are unusually reactive to any exposure. Rats administered oxalic acid at 2.5 and 5% in the diet for 70 days developed depressed thyroid function and weight loss. A study of railroad car cleaners in Norway who were heavily exposed to oxalic acid solutions and vapors revealed a 53% prevalence of urolithiasis (the formation of urinary stones), compared to a rate of 12% among unexposed workers from the same company. In a multigeneration study in mice, toxic effects in pups were seen only at maternally toxic doses. Oxalic acid is negative for genotoxicity in reverse mutation assays.

IF SWALLOWED, REFER FOR MEDICAL ATTENTION, WHERE POSSIBLE, WITHOUT DELAY. Where Medical attention is not immediately available or where the patient is more than 15 minutes from a hospital or unless instructed otherwise: For advice, contact a Poisons Information Center or a doctor. Urgent hospital treatment is likely to be needed. If conscious, give water to drink. INDUCE vomiting with fingers down the back of the throat, ONLY IF CONSCIOUS. Lean patient forward or place on left side (head-down position, if possible) to maintain open airway and prevent aspiration. NOTE: Wear a protective glove when inducing vomiting by mechanical means. In the mean time, qualified first-aid personnel should treat the patient following observation and employing supportive measures as indicated by the patient's condition. If the services of a medical officer or medical doctor are readily available, the patient should be placed in his/her care and a copy of the MSDS should be provided. Further action will be the responsibility of the medical specialist. If medical attention is not available on the worksite or surroundings send the patient to a hospital together with a copy of the MSDS. EYE ! If this product comes in contact with the eyes: Immediately hold eyelids apart and flush the eye continuously with running water. Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper and lower lids. Continue flushing until advised to stop by the Poisons Information Center or a doctor, or for at least 15 minutes. Transport to hospital or doctor without delay. Removal of contact lenses after an eye injury should only be undertaken by skilled personnel. SKIN ! If skin contact occurs: Immediately remove all contaminated clothing, including footwear Flush skin and hair with running water (and soap if available). Seek medical attention in event of irritation. INHALED ! If fumes or combustion products are inhaled remove from contaminated area. Lay patient down. Keep warm and rested. Prostheses such as false teeth, which may block airway, should be removed, where possible, prior to initiating first aid procedures. Apply artificial respiration if not breathing, preferably with a demand valve resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR if necessary. Transport to hospital, or doctor. NOTES TO PHYSICIAN ! Treatment must be prompt. Give immediately by mouth, a dilute solution of any soluble calcium salt; calcium lactate, lime water, finely pulverized chalk or plaster suspended in a large volume of water, milk. Large amounts of calcium are required to inactivate oxalate by precipitating it as the insoluble calcium salt. DO NOT give an emetic drug. Perform gastric lavage carefully or not at all if severe mucosal injury is evident. Dilute lime water (calcium hydroxide) makes a good lavage fluid if used in large quantity. Administer a slow intravenous injection of 10-20 ml of calcium gluconate (10% solution) or of calcium chloride (5% solution) This injection 3 of 12 Sodium oxalate sc-203396 Material Safety Data Sheet Hazard Alert Code Key: EXTREME HIGH MODERATE LOW may be repeated frequently to prevent hypocalcemic tetany. Calcium gluconate (10 m) may also be given intramuscularly every few hours. Calcium compounds are never given subcutaneously; even the intramuscular route is hazardous in infants because of the incidence of sloughing. In severe cases parathyroid extract (100 USP units) given intramuscularly.

  • Solvation Parameters for Sodium Oxalate in Mixed Ethanol-Water Solvents at 301.15 K
    Solvation parameters for sodium oxalate in aq. EtOH at 301.15 K Section A-Research Paper SOLVATION PARAMETERS FOR SODIUM OXALATE IN MIXED ETHANOL-WATER SOLVENTS AT 301.15 K Esam A.Gomaa[a] Keywords: molar solubility, sodium oxalate, free energies of solvation, water and ethanol The molar solubility of sodium oxalate (Na2Ox) in mixed ethanol (EtOH) – water solvent mixtures were measured at 301.15 K. From the molar solubilities, the activity coefficients, solubility products, free energies of solvation and the transfer free energies for the interaction of (Na2Ox) in mixed (EtOH-H2O) solvents were evaluated. *Corresponding Authors *E-mail: [email protected] [a] Chemistry Department , Faculty of Science, Mansoura University, Mansoura, EGYPT Introduction The solubility of solutes in mixed solvents is of great practical importance since many industrial processes as well as laboratory procedures need the use of solvent mixtures. We know that, the solubility of solutes in mixed solvents depends primarily on the solvation of solutes or their consitituent ions by the components of solvent mixture.1 Sodium oxalate, like citrate, can be used to remove calcium ions from blood plasma. This salt prevents blood clotting. Sodium oxalate can is responsible for the impairment of brain function, and deposit calcium oxalate in the kidneys.2 Solvation processes is also important to apply 3 for (Na2Ox) to understand its behaviour in solutions. Experimental Sodium oxalate (Na2Ox) and ethanol (EtOH) were supplied from Merck Co. Saturated solutions of (Na2Ox) were prepared by dissolving different amounts in closed test Figure 1. Solubility product (pK ), G (Gibbs free energy) tubes containing different EtOH-H2O mixtures.
