Question

Write a chemical equation for the dissociation of each of the following acids and bases in water, also identify the conjugate acid (CA) and conjugate base (CB)

a. Nitric acid
b. Ammonia

Answer 1

Nitric acid dissociates in water to form a proton (H+) and a nitrate ion (NO3-), with nitrate being the conjugate base. Ammonia reacts with water to form ammonium (NH4+) and hydroxide (OH-), with ammonium being the conjugate acid and hydroxide the conjugate base.

Step-by-step explanation:

The dissociation of nitric acid in water is represented by the following chemical equation:

HNO3(aq) → H+(aq) + NO3-(aq)

In this reaction, HNO3 is the acid that donates a proton (H+) to water, forming its conjugate base, NO3-, in the process.

The dissociation of ammonia in water is represented by:

NH3(aq) + H2O(l) → NH4+(aq) + OH-(aq)

Here, NH3 accepts a proton from water, forming its conjugate acid, NH4+, while water acts as an acid and its conjugate base is OH-.
