Question

A base, as defined by Bronsted theory, is a substance which can

Answer 1

By Bronsted's Theory , base are good proton acceptors.

Example :

$\mathsf{NH_3+H^{+}====>NH_{4}^{+}}$

Base is always a proton acceptor because it accepts the hydrogen ion of the acid hence forming water and salt.

By definition , base is a compound which reacts with the hydogen ions of an acid to form water and salt respectively.

Answer 2

A Brønsted-Lowry acid is any species that is capable of donating a proton— H+. A Brønsted-Lowry base is any species that is capable of accepting a proton, which requires a lone pair of electrons to bond to the H+. Water is amphoteric, which means it can act as both a Brønsted-Lowry acid and a Brønsted-Lowry base.
