4)Na2CO3 because it is basic in aqueous medium & so the pH>7 while KCl is a salt of strong acid & strong base(KOH+HCl)so its pH=7(NEUTRAL)
Similarly,NH4Cl is acidic & (NH4)2 CO3 Is also neutral.
Similarly,NH4Cl is acidic & (NH4)2 CO3 Is also neutral.

Answer:
Na2Co3 has high pH
Explanation:
High pH means more basic nature.
In 1. Kcl its is neutral salt.
2.Nh4cl its salt of strong acid.so its pH will be low.
3.(Nh4)2c03 ,it is also a salt of strong acid.
4.Na2Co3 is a salt of strong base ie,NaOH which highly basic. so its pH will be High
