Copper(I) ions in aqueous solution react with \( \mathrm{NH}_{3} \) (aq) according to \[ \mathrm{Cu}^{+}(\mathrm{aq})+2 \mathrm{NH}_{3}(\mathrm{aq}) \longrightarrow \mathrm{Cu}\left(\mathrm{NH}_{3}\right)_{2}^{+}(\mathrm{aq}) \quad K_{\mathrm{f}}=6.3 \times 10^{10} \] solubility of \( \mathrm{CuBr}(\mathrm{s}) \) :
