Ammonia (NH3) ionizes in water to form a basic solution. What is the concentration of OH- ions in a 0.75 M NH3 solution?

The concentration of ions in the solution is 0.0036 M

Explanation:

We are given:

Concentration of ammonia = 0.75 M

The chemical equation for the ionization of ammonia follows:

Initial:          0.75

At eqllm:    0.75-x                 x         x

The expression of for above equation follows:

We know that:

Putting values in above equation, we get:

Neglecting the negative value of 'x', because concentration cannot be negative

So, concentration of hydroxide ion = 0.0036 M

Hence, the concentration of ions in the solution is 0.0036 M
