Calcium sulfate is only sparingly soluble.
CaSO4(s) ⇌ Ca2+(aq) + SO42-(aq)
For this type of
dissolution reaction the equilibrium constant, also known as the solubility product, is denoted Ks.
In the reaction above, Ks = 4.9 x 10-6.
When an excess of the solid is dissolved in water what is the maximum concentration of Ca2+(aq) in mol L-1?
(Give your answer to at least TWO significant figures and do not include the units in the answer box. Hint: to help answer this question, first work out the mathematical equation for Ks in terms of the concentrations of the chemical species.)
