Chapter 21, Problem 19E

Without performing detailed calculations, indicate whether equilibrium is displaced either far to the left or far to the right for each of the following reactions. Use data from Appendix D as necessary.

1. ${\text{BaSO}}_{\text{4}}\left(\text{s}\right)+{\text{ CO}}_{\text{2}}{}^{2-}\left(\text{aq}\right){\text{=BaCO}}_{\text{2}}\left(\text{s}\right)+{\text{ SO}}_{\text{4}}{}^{2-}\left(\text{aq}\right)$
2. ${\text{Mg}}_{\text{2}}{\left({\text{PO}}_{\text{4}}\right)}_2\left(\text{s}\right)+{\text{3 CO}}_{\text{2}}{}^{2-}\left(\text{aq}\right){\text{=3 MgCO}}_{\text{2}}\left(\text{s}\right)+{\text{ 2 PO}}_{\text{4}}{}^{2-}\left(\text{aq}\right)$
3. $\text{Ca}{\left(\text{OH}\right)}_2+{\text{2 F}}^{\text{-}}\left(\text{aq}\right){\text{=CaF}}_{\text{2}}\left(\text{s}\right)+{\text{2 OH}}^{\text{-}}\left(\text{aq}\right)$
