# What concentration of SO32- is in equilibrium with Ag2SO3(s) and 9.60 * 10-3 M Ag ?

## Question:

What concentration of SO32- is in equilibrium with Ag2SO3(s) and 9.60 * 10-3 M Ag ?

## Molarity

Molar concentration is a measure of the concentration of a chemical species in terms of the amount of substance per unit volume of solution. The higher the molarity, the higher the concentration of the solute in the solution.

{eq}Ksp {/eq} of {eq}Ag_2SO_3 = 1.50 \times 10^{-14} {/eq}

{eq}Ag_2SO_3 \rightleftharpoons 2Ag^+ + SO_3^{2-} {/eq}

{eq}Ksp = [Ag^+]^2 \times [SO^{2-}_3] {/eq}

{eq}1.50 \times 10^{-14} = (9.60 \times 10^{-3})^2 [SO^{2-}_3] {/eq}

{eq}[SO^{2-}_3] =1.63 \times 10^{-10} M {/eq}

={eq}1.63 \times 10^{-10} M {/eq}
