Ответ:
The concentration of ammonia is 0.056 M
Explanation:
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,![pOH=14-11.00=3.00](/tpl/images/0135/3145/d7469.png)
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
