For an experiment on the effect of a buffer solution, I need to calculate the expected pH of the buffer.

Question

I know that I have to make an amounts table and use the Hasselbalch equation to find the pH.

For the first part, 0.10M HCl was added to a buffer. The first addition was 5 mL of the HCl.

Before doing the amounts table I know I have to find moles of HCl.
So 0.10M X 0.005 = 0.0005. Did I do this correctly?

Answer 1

yes
