Acetic acid is used as a solvent for some reactions between acids and bases. (a) Nitrous acid and carbonic acids are both weak acids in water. Will either of them act as a strong acid in acetic acid? Explain your answer. (b) Will ammonia act as a strong or weak base in acetic acid? Explain your answer.

Can someone explain why nitrous acid will act as a strong acid or ammonia as a strong base?

Nitrous acid acts like a strong acid because its conjugate base is weaker than the acetate ion that is present. This presence of acetate will shift the reaction towards the products which will increase the Ka of nitrous acid causing it to act like a strong base. I'd assume that it is the same for part b just instead the conjugate acid is weaker than acetic acid. Hope this helps.
