You need to produce a buffer solution that has a pH of 5.00. You already have a solution that contains 10. mmolmmol (millimoles) of acetic acid. How many millimoles of acetate (the conjugate base of acetic acid) will you need to add to this solution

Answer : The  millimoles of acetate need to add to this solution will be, 18.2 mmol

Explanation :

For acetic acid,

Moles of of acetic acid = 10 mmol

pH = 5.00

Using Henderson Hesselbach equation :

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

Thus, the millimoles of acetate need to add to this solution will be, 18.2 mmol
