Question

C2d3 has a solubility product constant of 9.14×10−9. what is the molar solubility of c2d3?

Answer 1

The correct answer for the question that is being presented above is this one:

We need to express the ksp expression of C2D3
C2D3
= (2x)2(3x)3
= 108x5

Then set that equation equal to your solubility constant

9.14x10-9 = 108x5
x = 9.67x10-3

So the molar solubility is 9.67x10-3
