Asked by Logan

Can the NH3/NH4Cl system be sued to prepare a buffer of a pH 9.5? why or why not? Can it prepare a buffer of pH 5? There were two buffers, 0.2 M and 0.1M.

I don't know how we can sue the NH3/NH4Cl system; however, the pKa for NH3 is 9.25 and that is within the range. What about the two buffers of 0.2M and 0.1M?

Thank you, it should say 'used' not 'sued'.

9.5 yes.
5 no.
