Sure! Let's identify each of the given substances:

1. SrSO4(s)
- This substance is SrSO4, known as strontium sulfate.
- Strontium sulfate is a salt formed from the reaction between strontium hydroxide (a base) and sulfuric acid (an acid).
- Therefore, SrSO4 is a salt.

2. H2SO4(aq)
- This substance is H2SO4, known as sulfuric acid.
- Sulfuric acid is a well-known acid that dissociates in water to produce hydrogen ions (H+) and sulfate ions (SO4^2-).
- According to the Arrhenius definition, an acid is a substance that increases the concentration of H+ ions in aqueous solution.
- Therefore, H2SO4 is an Arrhenius acid.

3. Sr(OH)2(s)
- This substance is Sr(OH)2, known as strontium hydroxide.
- Strontium hydroxide dissociates in water to produce strontium ions (Sr^2+) and hydroxide ions (OH-).
- According to the Arrhenius definition, a base is a substance that increases the concentration of OH- ions in aqueous solution.
- Therefore, Sr(OH)2 is an Arrhenius base.

To summarize:
- SrSO4(s) is a salt.
- H2SO4(aq) is an Arrhenius acid.
- Sr(OH)2(s) is an Arrhenius base.
