The reaction between magnesium hydroxide (Mg(OH)₂) and sulfuric acid (H₂SO₄) yields magnesium sulfate (MgSO₄) and water (H₂O).

Here's the balanced chemical equation:

Mg(OH)₂ + H₂SO₄ → MgSO₄ + 2H₂O

This reaction is a classic example of a neutralization reaction, where an acid (sulfuric acid) reacts with a base (magnesium hydroxide) to produce a salt (magnesium sulfate) and water.
