Question

Is ${\mathrm{SrSO}}_4$ soluble in water?

Answer 1

1. Strontium sulfate: It is a salt of strontium. The solubility of strontium sulfate$\mathbf{\left(}{\mathbf{SrSO}}_{\mathbf{4}}\mathbf{\right)}$ in water is 0.014gram/100ml at $30°\mathrm{C}$.
2. The solubility of strontium sulfate in water is very low.
3. The hydration enthalpy of strontium sulfate is very low so it is partially soluble (most of the time insoluble) in water.
4. It is soluble in hydrochloric acid and nitric acid.

Hence, Strontium sulfate $\mathbf{\left(}{\mathbf{SrSO}}_{\mathbf{4}}\mathbf{\right)}$ is considered insoluble in water.
