Answer:
According to the Arrhenius an acid and base react they form water and salt.
Explanation:
Neutralization reaction:
When an acid and base react they form water and salt.The reaction is called neutralization reaction.
According to the Arrhenius an acid is the substance which increase the H⁺ concentration, while base is the substance which increase the OH⁻ concentration.
General equation:
HX + BOH → BX + H₂O
From given reaction equations only option C is correct because only this reaction gives salt and water.
For example,
Chemical equation:
Ca(OH)₂ + H₂SO₄ → CaSO₄ + 2H₂O
Calcium hydroxide is acting as a base. Sulfuric acid is an acid. Both these reactants react to form salt which is calcium sulfate and water.
Calcium hydroxide dissociate to gives Ca²⁺ ion and OH⁻ while H₂SO₄ dissociate to gives H⁺ and SO₄²⁻. Ca²⁺ and SO₄²⁻ react to form salt CaSO₄ while OH⁻ and H⁺ form water.
