The aq stands for aqueous something that is dissolved in water.When placed in water the H+ will combine with H2O to form H3O+, the hydronium ion. Total change for 2 Mn aoms is 8. \\ A. acetic acid B. HCl C. H_2SO_4 D. None of these, Dicarboxylic acids have two dissociation constants, one for the initial dissociation into a monoanion and one for the second dissociation into a dianion. In the above reaction, dissociates to give hydrogen ions in the solution. Write balanced chemical equations for the sequence of reactions that oxalic acid can undergo when it's dissolved in water. (The book was written by my teacher, I suppose he made a mistake in this exercise). H2S, has two acid ionization constants. 3. the reaction of oxalic acid c ammonia solution: Oxalic acid reacts with ammonia dissolved in water.
