The chemical reaction given, H2SO4 (aq) + Sr(OH)2 (aq) → 2 H2O (l) + SrSO4 (s), is a double displacement reaction, also known as a precipitation reaction. In this reaction, the sulfate ion (SO4^2-) from sulfuric acid (H2SO4) combines with the strontium ion (Sr^2+) from strontium hydroxide (Sr(OH)2) to form an insoluble salt, strontium sulfate (SrSO4), which precipitates out of the solution as a solid. Meanwhile, water (H2O) is formed as a product of the reaction.
The overall reaction can be summarized as follows:
H2SO4 (aq) + Sr(OH)2 (aq) → 2 H2O (l) + SrSO4 (s)
This type of reaction is characteristic of double displacement reactions where the positive and negative ions in the reactants switch places to form new compounds.
