Acetic acid (CH3COOH) is a weak acid. BASE (wikipedia) Join. Both \(HCN\) and acetic acid are stronger acids than water, and hydroxide is a stronger base than either acetate or cyanide, so in both cases, the equilibrium lies to the left. Bade 2 Answers. What, A:Since in the above reaction, the molecule CH3CH2NH2 is gaining 1 H+ to form CH3CH2NH3+ and H2O is, A. basic, because of the hydrolysis of NO, B. acidic, because of the hydrolysis of NO, C. acidic, because of the hydrolysis of CH, D. basic, because of the ionization of CH, E. basic, because of the hydrolysis of CH.
