Consider the following reaction at 25 °c: cacro4s)-ca2*la)+cro,2(aq) ko 7.1 104 what are the equilibrium concentrations of ca2 and cro42?

The equilibrium concentration of are 0.0266 M.

Explanation:

The chemical equation for the ionization of calcium chromate follows:

The expression for equilibrium constant is given as:

We are given:

The concentration of solid substances are taken to be 1. Thus, they do not appear in the equilibrium constant expression.

Let the equilibrium concentration for be 'x'

Putting values in above equation, we get:

Hence, the equilibrium concentration of are 0.0266 M.
