Question

Aqueous lithium sulfate was mixed with aqueous strontium chlorate, and a crystallized strontium sulfate product was formed. What is the molecular equation for this?

Answer 1

2Li2SO4 + Sr(ClO3)2 --> Sr(ClO3)2 + Li2ClO3

Answer 2

Balanced chemical reaction:

Li₂SO₄(aq) + Sr(ClO₃)₂(aq) → SrSO₄(s) + 2LiClO₃(aq).

Ionic reaction:

2Li⁺(aq) + SO₄²⁻(aq) + Sr²⁺(aq) + 2ClO₃⁻(aq) → SrSO₄(s) + 2Li⁺(aq) + 2ClO₃⁻(aq).

Net ionic reaction: SO₄²⁻(aq) + Sr²⁺(aq) → SrSO₄(s).

Lithium sulfate (Li₂SO₄), strontium chlorate (SrClO₃) and lithium chlorate (LiClO₃) are salts dissolved in water. Strontium sulfate (SrSO₄) has low solubility in water.
