<u>Answer:</u> The concentration of ammonia is 0.056 M
<u>Explanation:</u>
To calculate the hydroxide ion concentration, we first calculate pOH of the solution, which is:
pH + pOH = 14
We are given:
pH = 11.00
So,
To calculate hydroxide ion concentration, we use the equation:
We know that:
pOH = 3.00
The chemical equation for the hydrolysis of ammonia follows:
Let the concentration of ammonia be 'x'
The expression of for above equation follows:
We are given:
Putting values in above expression, we get:
Hence, the concentration of ammonia is 0.056 M
