SCH$4$U $-$ Solubility Equilibrium Review

Consider the following salts: $,$Agl,$AgN{O}_3,$AgCl,$A{g}_{2}C{O}_3,A{g}_{2}Cr{O}_4$

a$)$ List these salts in order of increasing solubility.

b$)$ Write the chemical equilibrium equation for the formation of an aqueous solution of the least soluble silver salt.

c$)$ Determine the solubility in $mo\frac{l}{L}$ and in $\frac{g}{L}$ for the least soluble silver salt in pure water.

$($Ans: $9\mathrm{.}2{10}^{-9}mo\frac{l}{L}$ and $2\mathrm{.}2{10}^{-6}\frac{g}{L})$

d$)$Determine the solubility in $mo\frac{l}{L}$ for the least soluble silver salt in pure water in a $0\mathrm{.}025M$ solution containing a

sodium salt with the same negative ion. $($Ans: $3\mathrm{.}5{10}^{-15}mo\frac{l}{L})$
