Question

An aqueous solution of sodium chloride is neutral but on aqueous solution of sodium carbonate solution is basic explain

Answer 1

Answer:

NaCl is a salt which is neutral mance does not shows acidic or basic property in water but Na2Co3 IS metal carbonate and hence shows it's basic property in water.

Answer 2

Answer:

Because the sodium chloride is made up of complete neutralization of H+ and OH - .

Explanation:-

The aqueous solution of Nacl is neutral because it is made up of complete neutralization of an acid with base i.e, Complete neutralization of H+ and OH-.

or,it is made up of strong acid and base hence,it is neutral in aqueous solution.

Case 2 :-

In case of Na2CO3 the neutralization is not complete because it is made up of weak acid and strong base and it contains some amount of OH- which gives the property of base .

Hence,it is basic in its aqueous solution.
