Among the acids HClO4 is the strongest acid...... and HCN the weakest..... hence the the conjugate base is inverse.... Therefore CN- is th weakest acid

i think ans is d)...as it is the strongest base...in H₂SO₄ it makes the solution least acidic

CN^- is the strongest base as HCN is the weakest acid....i feel

@Vishal no dude in a the electrons are being delocalised over O atoms. Hence they are less available for donation and hence it can't be the strongest base........

Perchloric acid, HClO₄, is an oxoacid of chlorine and is a colorless liquid soluble in water. It is a strong acid comparable in strength to sulfuric and nitric acids. It is useful for preparing perchlorate salts, but it is also dangerously corrosive and readily forms explosive mixtures.

and ClO₄^- is the most stable oxoanion.

i htink this will help

I suppose u have interpreted the question differently.
U all are trying to find which is the strongest base which can reduce the acidity of Sulphuric acid but I think we have to find which is the weakest acid in H₂SO₄
Correct me if I'm wrong...
