Which of the following is more likely to precipitate the hydroxide ion?

1. $\text{Cu}{\left(\text{OH}\right)}_2\left(\text{s}\right)\rightleftarrows {\text{Cu}}^{2+}\left(\text{aq}\right)+{\text{2OH}}^{-}\left(aq\right)K=1.6\times {10}^{-19}$

$\text{Ca}{\left(\text{OH}\right)}_2\left(\text{s}\right)\rightleftarrows {\text{Ca}}^{2+}\left(\text{aq}\right)+{\text{2OH}}^{-}\left(aq\right)K=7.9\times {10}^{-6}$
