Explanation / Answer

According to Bronsted-Lowry, an acid is a proton donor and a base is a proton acceptor.

According to Lewis, an acid is a prootn acceptor and a base is a proton acceptor.

1) H2CO3 + H2O ----> H3O+ + HCO3-

H2CO3 = Bronsted acid , H2O = Bronsted base / Lewis base.

2) Ni2+ + 6NH3 ----> [Ni (NH3)6]2+

Ni2+ = Lewis acid , NH3 = Lewis base./ Bronsted base.

3) SO2 + 2 ClO3- ---> 2 ClO2 + SO42-

SO2 = Lewis acid , ClO3- = Lewis base

4) 2 HF + C3H7COOH ----> [C3H7C(OH)2]+ + HF2

HF = Bronsted acid/ Lewis acid , C3H7COOH = Bronsted base
