a) Calcium hydroxide reacts with nitric acid
- Ca(OH)₂ + 2HNO₃ → Ca(NO₃)₂ + 2H₂O
● Here Calcium Hydroxide reacts with nitric acid to form Calcium Nitrate and water
b) Acetic acid reacts with calcium hydroxide
- 2CH₃COOH + Ca(OH)₂ → Ca(OCOCH₃)₂ + 2H₂O
● Here Acetic acid reacts with Calcium Hydroxide to give Calcium Acetate and water is released
c) Hydrochloric acid reacts with sodium hydroxide
- NaOH + HCl → + NaCl + H₂O
● Here Hydrochloric acid reacts with Sodium hydroxide to give out Sodium chloride and water
d) Ammonium hydroxide reacts with sulphuric acid
- H₂SO₄ + 2NH₄OH → (NH₄)₂SO₄ + 2H₂O
● Here Ammonium hydroxide reacts with sulphuric acid to form Ammonium sulphate and water
