Benzoic acid is a weak acid, so it does not completely dissociate in water. Label each compound (reactant or product) in the equation with a variable to represent the unknown coefficients. When acids undergo dissociation, they produce hydrogen ions. Nitrous acid (HNO2) is a weak acid. H2CO3 <--> H+ + HCO3-. Helmenstine, Anne Marie, Ph.D. "Dissociation Reaction Definition and Examples." As a result, the Ka expression is: Ka = ( [H+] [HCO3-])/ [H2CO3] It should be noted that carbonic acid is a weak acid, so its Ka value in water is only 4.3 x 10^-7. b) Most fruits contain weak acids. The chemical equation for the first dissociation of carbonic acid follows: Using the Bronsted-Lowry definition of acids and bases, identify the reactants in the following reaction as an acid or base. ; Flow Machine + H2O ( l ) arrow H2SO3 ( aq ) ).
