Chapter 15, Problem 53QAP

For the reaction

${\text{CdC}}_2{\text{O}}_4+4{\text{NH}}_3\left(aq\right)\rightleftharpoons \text{Cd}{\left({\text{NH}}_3\right)}_4{}^{2+}\left(aq\right)+{\text{C}}_{\text{2}}{\text{O}}_4{}^{2-}\left(aq\right)$

(a) calculate K. (K_sp for CdC₂O₄ is $1.5\times {10}^{-8}$.)

(b) calculate [NH₃] at equilibrium when 2.00 g of CdC₂O₄ are dissolved in 1.00 L of solution.
