###### Question

C2D3 has a solubility product constant of 9.14 x 10 -9. What is the molar solubilty of C2D3?

# Solution: C2D3 has a solubility product constant of 9.14 x 10 -9. What...

$C_2D_3$ is going to be a solid, meaning it will dissociate completely as follows:

$C_2D_{3(s)} \rightarrow 2\ C^{3+}_{(aq)} + 3\ D^{2-} _{(aq)}$

To find the molar solubility (x), me must assume:

$C_2D_3 \rightarrow 2X + 3X$

The equilibrium expression for Ksp is:
