What are the concentrations of hydrogen ion and hydroxide ion in household ammonia

This is an incomplete question, here is a complete question.

What are the concentrations of hydrogen ion and hydroxide ion in household ammonia, an aqueous solution of NH₃ that has a pH of 11.00?

Answer : The concentrations of hydrogen ion and hydroxide ion in household ammonia is, and

Explanation :

As we know that the aqueous solution of ammonia is ammonium hydroxide that is,

The equilibrium reaction will be:

Given:

pH = 11.00

First we have to calculate the hydrogen ion concentration.

pH : It is defined as the negative logarithm of hydrogen ion concentration.

Now we have to calculate the pOH.

Now we have to calculate the hydroxide ion concentration.

Therefore, the concentrations of hydrogen ion and hydroxide ion in household ammonia is, and
