Concepts and reason

The concept used to solve this problem is determined the Conjugated acid-Base.

Fundamentals

Bronsted-Lowry acid-base system:

Acid:

According to Bronsted-Lowry; acid is a substance that donates theĀ (hydrogen ion) or proton. In general Bronsted-Lowry acid is a proton donor.

Base:

According to Bronsted-Lowry; base is a substance that accepts theĀ Ā (hydrogen ion) or proton. In general Bronsted-Lowry base is a proton acceptor.

HCI + NH, NH +CI
Acid base

Conjugated acid-Base Pairs:

The pair of Acid-Base which is differs by a proton is called conjugated Acid-Base pair. The acid of conjugated acid-base pair has one more hydrogen atom from base of conjugated acid-base pair.

HCI+NH,
Acid base
NH + CI

After donate one proton from an acid conjugate base will form; thus,Ā Ā is the conjugate base ofĀ .
