The Na+ ion weakly polarizes its water lig- ands provided there are metal ions in solution. Sodium sulfate reacts with sulfuric acid to give the acid salt sodium bisulfate, leading ot a temperatude-dependant equi- librium: Na2SO4 + H2SO4 ⇌ 2 NaHSO4 2− Sulfate ions (SO4 ) in solution can be indicated by the easy formation of insoluble sulfates when these solutions are treated with Ba2+ or Pb2+ salts: Na2SO4 + BaCl2 → 2 NaCl + BaSO4 Double salts with some other alkali metal sulfates are known, including Na2SO4·3K2SO4. -

The CuxO/TiO2 nanoparticulate photocatalyst was sequentially sputtered on polyester (PES). The photocatalyst formulation was optimized by investigating the effect of different parameters such as the sputtering time of CuxO, the applied current, and the deposition mode (direct current magnetron sputtering, DCMS or HiPIMS). -
Working with Hazardous Chemicals
A Publication of Reliable Methods for the Preparation of Organic Compounds Working with Hazardous Chemicals The procedures in Organic Syntheses are intended for use only by persons with proper training in experimental organic chemistry. All hazardous materials should be handled using the standard procedures for work with chemicals described in references such as "Prudent Practices in the Laboratory" (The National Academies Press, Washington, D.C., 2011; the full text can be accessed free of charge at http://www.nap.edu/catalog.php?record_id=12654). All chemical waste should be disposed of in accordance with local regulations. For general guidelines for the management of chemical waste, see Chapter 8 of Prudent Practices. In some articles in Organic Syntheses, chemical-specific hazards are highlighted in red “Caution Notes” within a procedure. It is important to recognize that the absence of a caution note does not imply that no significant hazards are associated with the chemicals involved in that procedure. Prior to performing a reaction, a thorough risk assessment should be carried out that includes a review of the potential hazards associated with each chemical and experimental operation on the scale that is planned for the procedure. Guidelines for carrying out a risk assessment and for analyzing the hazards associated with chemicals can be found in Chapter 4 of Prudent Practices. The procedures described in Organic Syntheses are provided as published and are conducted at one's own risk. Organic Syntheses, Inc., its Editors, and its Board of Directors do not warrant or guarantee the safety of individuals using these procedures and hereby disclaim any liability for any injuries or damages claimed to have resulted from or related in any way to the procedures herein. -

Production of Dialdehyde Cellulose and Periodate Regeneration: Towards Feasible Oxidation Processes
Production of Dialdehyde Cellulose and Periodate Regeneration: Towards feasible oxidation processes Produktion av dialdehydcellulosa och återgenerering av perjodat: Mot möjliga oxidationsprocesser Elisabeth Höglund Department of Engineering and Chemical Sciences Chemistry 30 hp Supervisors: Susanne Hansson, Stora Enso & Gunilla Carlsson, Karlstad University Examinator: Thomas Nilsson 2015-09-25 ABSTRACT Cellulose is an attractive raw material that has lately become more interesting thanks to its degradability and renewability and the environmental awareness of our society. With the intention to find new material properties and applications, studies on cellulose derivatization have increased. Dialdehyde cellulose (DAC) is a derivative that is produced by selective cleavage of the C2-C3 bond in an anhydroglucose unit in the cellulose chain, utilizing sodium periodate (NaIO4) that works as a strong oxidant. At a fixed temperature, the reaction time as well as the amount of added periodate affect the resulting aldehyde content. DAC has shown to have promising properties, and by disintegrating the dialdehyde fibers into fibrils, thin films with extraordinary oxygen barrier at high humidity can be achieved. Normally, barrier properties of polysccharide films deteriorate at higher humidity due to their hygroscopic character. This DAC barrier could therefore be a potential environmentally-friendly replacement for aluminum which is utilized in many food packages today. The aim of this study was to investigate the possibilities to produce dialdehyde cellulose at an industrial level, where the regeneration of consumed periodate plays a significant role to obtain a feasible process. A screening of the periodate oxidation of cellulose containing seven experiments was conducted by employing the program MODDE for experimental design. -
Understanding the Basics of Electron Transfer and Cyclic Voltammetry of Potassium Ferricyanide - an Outer Sphere Heterogeneous Electrode Reaction
Sayyar Muhammad et al., J.Chem.Soc.Pak., Vol. 42, No. 06, 2020 813 Understanding the Basics of Electron Transfer and Cyclic Voltammetry of Potassium Ferricyanide - An Outer Sphere Heterogeneous Electrode Reaction 1Sayyar Muhammad*, 1Ummul Banin Zahra, 1Aneela Ahmad, 2Luqman Ali Shah and 1Akhtar Muhammad 1Department of Chemistry, Islamia College Peshawar, Peshawar-25120, Pakistan. 2National Centre of Excellence in Physical Chemistry, University of Peshawar, Peshawar-25120, Pakistan. [email protected]* (Received on 5th December 2019, accepted in revised form 11th August 2020) Summary: Understanding and controlling the processes occurring at electrode/electrolyte interface are very important in optimizing energy conversion devices. Cyclic voltammetry is a very sophisticated and accurate electroanalytical method enables us to explore the mechanism of such electrode reactions. In this work, electrochemical experiments using cyclic voltammetry were performed in aqueous KCl solution containing potassium ferricyanide, K3[Fe(CN)6] at a glassy carbon disc working electrode and the mechanism of the reactions is highlighted. The CV 3− 4− measurements shows that the ferricyanide [Fe(CN)6] reduction to ferrocyanide [Fe(CN)6] and the reverse oxidation process follows an outer sphere electrode reaction mechanism. Voltammetry analysis further indicates that the reaction is reversible and diffusion controlled one electron transfer 4− electrochemical process. The peak currents due to [Fe(CN)6] oxidation and the peak current due to 3− [Fe(CN)6] reduction increase with increase of concentration and scan rate increase. The diffusion co-efficient was determined by applying Randles-Sevcik equation. The report could be helpful for university students to understand the basics of electron transfer in redox processes and cyclic voltammetry. -
