Determine the ammonia concentration of an aqueous solution that has a ph of 11.00. the equation for the dissociation of nh3 (kb = 1.8 × 10-5) is determine the ammonia concentration of an aqueous solution that has a ph of 11.00. the equation for the dissociation of nh3 (kb = 1.8 × 10-5) is 1.8 × 10-2 m

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,

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
