A solution is made by dissolving 0.63 gm of nitric acid in 200 ml of water, assuming that the acid is completely dissociated, calculate its pH value.

Expert Answer
Molarity of the solution = w/m/V in litre = 0.63/63/.2 = .05 M
Hence [H3O+] = 5.0 X 10-2 (assuming that the acid is completely dissociated)
pH = - log[H3O+]
= 1.30
