Chapter 18, Problem 58E

Question 57 and 58: In Chapter 9, we discussed how to identify major and minor species and how to write net ionic equations. These skills are based on the solubility of ionic compounds, the strengths of acids, and the stability of certain ion combinations. Use these ideas to predict the favored direction of each equilibrium given. In each case, state whether you expect the equilibrium concentration to be large or small.

a). $\text{HCl}\left(\text{aq}\right)\rightleftharpoons {\text{H}}^{+}\left(\text{aq}\right)+{\text{Cl}}^{-}\left(\text{aq}\right)$

b) ${\text{BaSO}}_4\left(\text{s}\right)\rightleftharpoons {\text{Ba}}^{2+}\left(\text{aq}\right)+{\text{SO}}_4{}^{2-}\left(\text{aq}\right)$
