Hey,

I have a question a given solution but i don't understand how it was obtained. The only methods I can find have the concentration of the buffer solution given. We have been taught how to deal with this when the concentrations are the same (for the acetic acid and NaOH), but I am struggling as the concentrations of these solutions are different. I'm a little lost

Thanks in advance.

oops. forgot the scanner saved as pdf by default. Here's the image of my working incase it's a pain. PS: it's just a follow up quiz not the assignment component, the name came from the previous scan.

Not sure what your problem is, as you wrote n=CV on the side of the scan - that (plus HH equation) is all that you need in order to solve the problem, you need just a small modifications of the process. Final volume is sum of volumes (which actually doesn't matter, but may help you).

It is just about stoichiometry and assuming reaction went to completion.

I feel a little stupid. the error was in using the incorrect value for the concentration of acetic acid. Thanks for the help
