11. 1. 2. (a) (b) QUESTIONS Define the term "dissolution". In an aqueous solution of sodium carbonate, Na2CO3, the following equilibrium occurs: CO3(aq) + HO(1) HCO3(aq) + OH (aq) (b) (a) How would the addition of solid sodium carbonate, NaCO3, affect the equilibrium? Briefly explain your answer. W (D 3. If a saturated solution of sodium nitrate, NaNO3, is prepared, the following equilibrium exists: NaNO3(s) Nat(aq) + NO3(aq) If nitric acid is added to the saturated solution, what will happen to the equilibrium? Briefly explain your answer. If a small volume of concentrated HCl solution were added, how would the equilibrium be changed? Briefly explain your answer. The dissolution of NaNO3 is endothermic. What change in temperature conditions would cause more NaNO3(s) to dissolve? Briefly explain your
