Question

classify the following salts into acidic, basic and neutral: potassium sulphate, ammonium chloride, sodium carbonate, sodium chloride.

Answer 1

K2SO4 : Neutral salt.
NH4Cl : Acidic salt.
Na2CO3 : Basic salt.
NaCl : Neutral salt.

Answer 2

Potassium sulphate(K₂SO₄) is neutral as it is a salt of a strong acid(H₂SO₄) and a strong base(KOH).

Ammonium chloride(NH₄Cl) is acidic as it is a salt of strong acid(HCl) and weak base(NH₄OH).

Sodium carbonate(Na₂CO₃) is basic as it is a salt of weak acid(H₂CO₃) and strong base(NaOH).

Sodium chloride(NaCl) is neutral as it is a salt of strong acid(HCl) and strong base(NaOH).
