suppose 1.0mL of 0.1 M HCl is added to 0.15 M CH3COO and 0.10 M CH3COOH (two are in one solution)?

Question

- what will be the new concentration of CH3COOH and CH3COO in the buffer solution upon addition of 1.0mL of 0.1 M HCl?

-Calculate the new pH of the buffer.


i'll wait for the answers...=^_^=

Answer 1

You need to know the volume of the solution you're starting with, because you have to be able to figure out how many moles of acetate will react with the HCl to form acetic acid.
