1. Test Reagent: CH,COONa a. Write the equilibrium equation for the dissociation of CH,COONa in water. b. What is the initial effect on the acetic acid equilibrium when CH,COONa is added? According to Le Châtelier's principle, how does the acetic acid dis- sociation equilibrium shift in response to the addition of CH3COONa? What is the overall change in [H3O+] in the solution? (Consider the color change of the indicator.) How would one explain this change based on the shift of...

Write the chemical equation for the dissolution of calcium hydroxide in water, and write its corresponding K_sp equilibrium expression. Write the balanced chemical equation for the reaction of HCl with calcium hydroxide, which yields water and calcium chloride.

Review equation 16.10 and step B2. Ag+1(aq) and NH3(aq) will form a soluble complex ion. Use rule 3 of Water-Insoluble Salts in Appendix E to determine what would happen if Ag+1(aq) was combined with KOH instead of NH3. Write the net ionic equation with phase subscripts, where K+1 is a spectator ion which is cancelled out. Equation 16.10: Ag^+(aq) + Cl^-(aq) ⇄ AgCl(s) ⇅ 2NH3(aq) [Ag(NH3)2]^+(aq) Step B2: Silver Chloride equilibrium. To the clear solution from part B.1, add 5...
