2H(+) + SO4(2-) + Ca(2+) + 2I(-) -> CaSO4(s) + 2H(+) + 2I(-)
The signs in brackets are the subscripts for the charge of the ion. This is the complete ionic equation. The net ionic equation is:
Ca(2+) + SO4(2-) -> CaSO4

Answer:

SO₄²⁻(aq) + Ca²⁺(aq) → CaSO₄(s)

Explanation:

Given equation:

H₂SO₄(aq) + Cal₂(aq) → CaSO₄(s) + 2HI(aq)

Ionic equation:

2H⁺(aq) + SO₄²⁻(aq) + Ca²⁺(aq) + 2I⁻(aq) → CaSO₄(s) + 2H⁺ (aq) + 2I⁻(aq)

Net ionic equation:

SO₄²⁻(aq) + Ca²⁺(aq) → CaSO₄(s)

2H⁺ (aq) and 2I⁻(aq) ions are common on both side of the equation hence they were eliminated. (aq) here means that the ions are in aqueous phase and (s) means solid or precipitate. CaSO₄ forms a white precipitate which does not ionize in the aqueous phase.
