Answer
Sodium hydroxide reacts with dilute H₂SO₄
Reason — A neutralization reaction occurs when an acid reacts with a base to form water and salt. In this case, sodium hydroxide (NaOH) is a base, and dilute sulfuric acid (H₂SO₄) is an acid. When they react, they form water (H₂O) and sodium sulphate (Na₂SO₄), which is a salt.
2NaOH(aq) + H2SO4(aq) → Na2SO4(aq) + 2H2O(l)
