Question

Define Bronsted-Lowry base and explain with an example that water is a Bronsted-Lowry base.

Answer 1

Answer. According to Bronsted-Lowry concept, a base is a substance that can accept a proton (H+) from another substance.
For example, when HC1 dissolves in water; HC1 acts as an acid and H2O as a base because it takes proton from HC1.
HCl(aq) + H2O(aq)   —————>   H3O+  (aq) + Cl- (aq)
Acid    Base                     Conjugate acid     Conjugate base
