Question

An aqueous solution of sodium chloride is neutral bit that of sodium carbonate is basic why

Answer 1

NaCl is salt of strong acid HCl and strong base NaOH. ... On other hand,sodium carbonate is a salt of weak acid H₂CO₃ and strong base NaOH. When it is dissolved in water,it undergo anionic hydrolysis.Thus salt solution contains OH- ions.

Answer 2

Sodium Chloride (NaCl) is a salt so when it is dissolved in water it is nuetral while Sodium Carbonate (Na2CO3) is a base so when dissolved in water the OH- ions show their properties and hence it is basic
