Asolution is prepared at that is initially in methylamine , a weak base with , and in methylammonium chloride . calculate the ph of the solution. round your answer to decimal places.

The question is incomplete, here is a complete question.

A solution is prepared at 25 °C that is initially 0.18 M in methylamine (CH₃NH₂), a weak base with , and 0.35 M in methylammonium bromide (CH₃NH₃Br). Calculate the pH of the solution. Round your answer to 2 decimal places.

Answer : The pH of the solution is, 10.36

Explanation :

First we have to calculate the value of .

Now we have to calculate the value of pOH.

Using Henderson Hesselbach equation :

Now put all the given values in this equation, we get :

Now we have to calculate the pH.

Therefore, the pH of the solution is, 10.36
