Question

Write chemical equations for the following reactions:
(a) Calcium hydroxide reacts with nitric acid.
(b) Acetic acid reacts with calcium hydroxide.
(c) Hydrochloric acid reacts with sodium hydroxide.
(0)
Ammonium hydroxide reacts with sulphuric acid.​

Answer 1

(a) Ca(OH)2 + 2HNO3 → Ca(NO3)2 + 2H2O.

(b) Ethanoic acid is the systematic name for acetic acid (CH3COOH) . The formula for calcium hydroxide is Ca(OH)2 . Balanced word equation: Two moles of ethanoic acid (acetic acid) react with one mole of calcium hydroxide to produce one mole of calcium acetate and two moles of water.

(c) acid + alkali → salt + water

(d) 2NH4OH + H2SO4----> (NH4)2SO2+ 2H2O.
