•The pKa for acetic acid is 4.756 and the pKa for NH4+ is 9.245. What pH do you expect for the solutions with [A-]init [HA]init? Explain this by referring to the acid = dissociation constant expressions (Ka) for NH4+ and CH3COOH as well as your answer to part (a). Do your measurements agree with your expectations (make specific reference to your experimental data and consider uncertainty)?
