4. What conditions need to be present in order for the Henderson- Hasselbach equation to be used?

pH=pKa+log [A-]/[HA]

A- There needs to be equal amounts of an acid and a base.

B- Only a salt that contains non-spectator ions needs to be present.

C- There has to be conjugate pairs both initially present in the solution.

the pka for p-nitrophenol is 6.0. Using the Henderson-Hasselbach equation determine what the ration of the deprotonated to protonated forms will be at pH 12.

Please show work. Thank you
