Question

The solubility product for an insoluble salt with the formula M2X3 is written as ________, where s is the molar solubility

Answer 1

36s^5

Step-by-step explanation:

We have;

M2X3 (s)------> 2M^3+(aq) + 3X^2-(aq)

If [M^3+(aq)] = [X^2-(aq)] = s

We then have;

Ksp = (2s)^2 * (3s)^3

Ksp = 4s^2 * 9s^3

Ksp = 36s^5

Note that Ksp is known as the solubility product. It is an equilibrum equation that shows the solubility of a solute in water.
