Hello,
At first, the answer is wrong, consider the following procedure:
- the pKs, leads to a Ks of:
- now, stating the equilibrium for the calcium sulfate (whereas x is the change during the equilibrium):
- x becomes the concentration of calcium ions and one of the contributions for the total concentration of sulfate ions, thus:
- finally, since the sodium sulfate is totally dissolved, we just simply add its concentration (equal to the sulfate ions yielded by itself) to the outgoing sulfate concentration from the calcium sulfate:
