The aqueous solution of sodium chloride
is neutral because it is formed from a
strong acid and a strong base.
Reaction: NaOH+HCl-NaCl+H

The aqueous solution of sodium
carbonate is basic because it gets
hydrolysed to some extent and forms
sodium hydroxide which is a strong base
and carbonic acid which is a weak acid.
