A. Gallium hydroxide like aluminum hydroxide is amphoteric. Write a balanced equation to show how this hydroxide can dissolve in both HCl(aq) as well as NaOH(aq).B. Gallium ion in water, Ga3+ (aq), has a Ka value of 1.2 x 10-3. Is this ion a stronger or else a weaker acid than Al^3+ (aq)?
Its titrated with NaOH. Being a triprotic and having 3 acid dissociation constants Ka1, Ka2, Ka3 one would expect to see three equivalence points. Why does it only show two equivalence points
