Question

Can someone help with this question.

The buffer capacity is defined as the anount of moles of acid or base needed to change the pH by 1 unit. If a strong acid is added to a buffer system will the pH increase or decrease by one unit when the buffer capacity is reached?

Answer 1

Adding a strong acid to any solution that is not a stronger acid will always make the pH decrease.

Answer 2

So if I add a conjugate base to the system to increase the pH of 1 or more the conjugate acid will have to deplete in order to maintain a certain pH right?

Answer 3

That sounds right to me.

Answer 4

Awesome. Thanks.

Answer 5

No worries.
