Explanation:
Hello there!
In this case, given the solubility equilibrium of strontium sulfate:
Whose equilibrium expression is:
In such a way, we can introduce the molar solubility, s, in the equation to obtain:
Then, we apply the square root to obtain:
Which is also the concentration of strontium ions:
