A 0.010 M aqueous solution of the weak acid, m-Nitrophenol (C6H4NO2OH) has a pH of 3.44. Calculate the Ka-value as well as pKa-value for the acid. Type your answer for the Ka-value as a scientific notation with 2 decimal places and for the pKa-value as a normal value with 2 decimal places. C6H4NO2OH (aq) + H2O (liquid) ⇔ C6H4NO2O- (aq) + H3O+ (aq) Ka = pKa =
