?At \(25^{\circ} \mathrm{C}\), the reaction\(\mathrm{CaCrO}_{4}(s) \rightleftharpoons

Chapter 15, Problem 15.58

(choose chapter or problem)

At \(25^{\circ} \mathrm{C}\), the reaction

\(\mathrm{CaCrO}_{4}(s) \rightleftharpoons \mathrm{Ca}^{2+}(a q)+\mathrm{CrO}_{4}^{2-}(a q)\)

has an equilibrium constant \(K_{c}=7.1 \times 10^{-4}\). What are the equilibrium concentrations of \(\mathrm{Ca}^{2+}\) and \(\mathrm{CrO}_{4}^{2-}\) in a saturated solution of \(\mathrm{CaCrO}_{4}\) ?

Text Transcription:

25^circ C

CaCrO_4(s) \rightleftharpoons Ca^2+(a q)+CrO_4^2-(a q)

K_c=7.1 \times 10^-4

Ca^2+

CrO_4^2-

CaCrO_4
