Question

Conc h2so4 or cacl2 or p4o10 cannot use in drying of ammonia why

Answer 1

Conc H₂SO₄ or CaCl₂ or P₄O₁₀ cannot use in drying of ammonia because these chemicals are strong acid and ammonia is a strong base, hence a reaction between acid and base will form salt .

For example the reaction between H₂SO₄ and ammonia(NH₃)

2NH₃ + H₂SO₄ ---------> (NH₄)₂SO₄

Hence ammonia will no longer be in its natural state and become a salt, hence Conc H₂SO₄ or CaCl₂ or P₄O₁₀ are not user for drying ammonia.
