Names and K, values for four weak acids are listed below. The Acid Dissociation equilibrium constant (Ka) describes the extent to which the acid dissociates in water: HA (aq) + H₂O (l) <=> H3O+ (aq) + A- (aq) If a 0.10 M solution is made of each acid, which solution would have the lowest pH? A. Acetic acid (CH3COOH), K₂ = 1.8 x 10-5 B. hydrofluoric acid (HF), K₂ = 6.6 x 10-4 C. carbonic acid (H₂CO3), K₂ = 4.3 x 10-7 D.hypochlorous acid (HOCI), K₂ = 2.9 x 108
