<u>Answer:</u> The pH of the solution is 11.24
<u>Explanation:</u>
We are given:
Molarity of ammonia = 0.2 M
The given chemical equation follows:
I: 0.2
C: -x +x +x
E: 0.2-x x x
The expression for equilibrium constant follows:
Putting values in above expression, we get:
Neglecting the negative value of x as concentration cannot be negative.
So,
pOH is defined as the negative logarithm of hydroxide ion concentration present in the solution.
Putting values in above equation, we get:
We know:
Hence, the pH of the solution is 11.24
