How would you account for the following:H_2Sis more acidic than HP_2O.

Answer»

SOLUTION :`H_2S` is more acidic than `H_2O`. This can be EXPLAINED in terms of their BOND energies. Bond energy of H - O bond is more than that of H - S bond. It is more DIFFICULT to break H - O bond to liberate `H^(+)` IONS.
