  • Writing Total and Net Ionic Equations
    WRITING TOTAL AND NET IONIC EQUATIONS http://www.csun.edu/~hcchm001/FreshChemHandouts.html 1. Write the overall equation including the correct designations for the physical state of the substances (s, l, g, aq). Balance this equation. Most of these kinds of equations are double displacement reactions: AX + BY 6 AY + BX 2. For the total ionic equations, write strong electrolytes in solution in the form of aqueous ions. (a) Strong acids. The common strong acids and their aqueous ions are: HI Hydroiodic acid H+-(aq) + I (aq) HBr Hydrobromic acid H+-(aq) + Br (aq) HCl Hydrochloric acid H+-(aq) + Cl (aq) +- HNO33Nitric acid H (aq) + NO (aq) +- HClO44Perchloric acid H (aq) + ClO (aq) +-2 H24SO Sulfuric acid 2 H (aq) + SO4(aq) (b) Strong bases. Strong bases are the hydroxides of the alkali (Group IA) and alkaline earth (Group IIA) metals ions which are sufficiently soluble. The common strong bases and their aqueous ions are: LiOH Lithium hydroxide Li+-(aq) + OH (aq) NaOH Sodium hydroxide Na+-(aq) + OH (aq) KOH Potassium hydroxide K+-(aq) + OH (aq) +2 - Sr(OH)2Strontium hydroxide Sr (aq) + 2 OH (aq) +2 - Ba(OH)2 Barium hydroxide Ba (aq) + 2 OH (aq) (c) Soluble salts. Determinations of the solubility of a salt may be made by reference to SOLUBILITIES OF IONIC COMPOUNDS. Soluble salts are written as their aqueous ions: NaCl(aq) Sodium chloride Na+-(aq) + Cl (aq) +-2 K24SO (aq) Potassium sulfate 2 K (aq) + SO4(aq) +-2 Li23CO (aq) Lithium carbonate 2 Li (aq) + CO3(aq) +-3 Na34PO (aq) Sodium phosphate 3 Na (aq) + PO4(aq) +-2 (NH42) SO4(aq) Ammonium sulfate 2 NH4(aq) + SO4 (aq) 3.

  • Determination of the Solubility Product of Groupii Hydroxides
    DETERMINATION OF THE SOLUBILITY PRODUCT OF GROUPII HYDROXIDES INTRODUCTION SOLUBILTY EQUILIBRIA Many systems in chemistry appear to be static when in fact they are in (dynamic) equilibrium. When a system is in dynamic equilibrium the rate of the forward process is equal to the rate of the reverse process. One of these equilibrium systems is solubility equilibrium. When an ionic salt is placed in water if the salt is soluble then the salt will break apart (dissociate) into ions and the solution will contain hydrated positive ions and hydrated negative ions. An example is the formation of Na+ (aq) and Cl- (aq) when NaCl is dissolved in water. Consulting solubility tables tell us that most hydroxides are insoluble and therefore do not dissociate into ions when in solution. For example the net ionic equation for the reaction between MgCl2 and KOH is shown below. (Equation 1, Figure 1). 2+ - Mg (aq) + 2(OH ) (aq) Mg(OH)2 (Equation 1) Figure (1) However, even compounds considered insoluble will form a small amount of ions in solution. If a salt is “insoluble” what is really happening is that the equilibrium for the formation of hydrated ions from the reaction between the solid salt and water lies very far to the left (toward the solid). The formation of this small amount of ions and their recombination make up a system in dynamic equilibrium. The equilibrium constant for this process is called the solubility product, Ksp. The equilibrium reaction and equilibrium constant expression for Mg(OH)2 is shown below. (Note that the Mg(OH)2 does not appear in the equilibrium expression since it is a solid.

  • Synthesis of Sro–Al2o3 Solid Base Catalysts from Strontium Hydroxide and Aluminum Alkoxide by a Solid-Liquid Interface Reaction
    Journal of the Japan Petroleum Institute, 64, (2), 103-111 (2021) 103 [Regular Paper] Synthesis of SrO–Al2O3 Solid Base Catalysts from Strontium Hydroxide and Aluminum Alkoxide by a Solid-liquid Interface Reaction Hiromi MATSUHASHI†1)*, Asako IWAMOTO†1), Misaho SASAKI†1), Kana YOSHIDA†1), and Hirofumi ARITANI†2) †1) Dept. of Science, Hokkaido University of Education, 1-2 Hachiman-cho, Hakodate, Hokkaido 040-8567, JAPAN †2) Dept. of Life Science & Green Chemistry, Faculty of Engineering, Saitama Institute of Technology, 1690 Fusaiji, Fukaya, Saitama 369-0293, JAPAN (Received October 19, 2020) _ Highly dispersed SrO in amorphous Al2O3, SrO Al2O3, was synthesized by solid-liquid interface reaction of Sr(OH)2・8H2O in the solid phase with Al(OCH(CH3)2)3 dissolved in 2-propanol. The water of crystallization in _ Sr(OH)2・8H2O was consumed for the hydrolysis of Al(OCH(CH3)2)3. SrO Al2O3 catalyst synthesized by solid-liquid interface reaction of equimolar amounts of Sr(OH)2・8H2O and Al(OCH(CH3)2)3, then heat treated at 673 K, exhibited the highest activity among the prepared catalysts for the base-catalyzed retro-aldol reaction of _ _ diacetone alcohol. Catalytic activity of SrO Al2O3 catalyst calcined at 673 K was twice that of SrO Al2O3 cata- _ lyst prepared by physical mixing of Sr(OH)2・8H2O with Al2O3. Active SrO Al2O3 catalyst was obtained by heating at a temperature just below that of Sr3Al2O6 crystallization. Formation of SrO by heat treatment at 673 K was confirmed using X-ray absorption near edge structure analysis.
