The pH of a 0.01 M solution of a monobasic acid is four. Which one of the following statement about the acid is incorrect

Concentration of monobasic acid = 0.01 MpH = 4If the acid is completely ionized, the pH of the acid would bepH=-log 0.01=-log 10-2=2As PH given is 4,So it is a weak acid. When the sodium salt of a weak acid is dissolved, the anions will be hydrolyzed giving rise to OH- ion concentration. The solution will be basic. So statement (c) is incorrect.
