Question

Consider a monohydrogen phosphate ( HPO42-) and dihydrogen phosphate (H2PO4-) buffer solution.

[HPO42-] = 0.063M

[H2PO4-] = 0.10M

What happens when you add 1.0 ml of 0.10 M HCl to the a 99ml solution?

What would the pH of the solution be without the buffer?

What would the pH of the solution be with the buffer?

Answer

For your answer you will need to go beyond simply filling in the formula and giving me a number.


You will need to convince me that you know what is going on here. Words are required for the explanation not just numbers.
