Based on these values, deduce the formula to compute the base dissociation constants of oxalate ion in terms of Kw and Ka1 or Ka2. The oxalate ion has a charge of minus 2. The steps and expressions fot the ionization constants for oxalic acid are given by these equations: Ka = [HO (aq)] [HCO (aq)] / [HCO(aq)], Ka = [HO (aq)] [CO (aq)] / [HCO (aq)]. Got fleeced as a Private Candidate. Compound states [like (s) (aq) or (g)] are not required. For oxalic acid, HO_2C - CO_2H, the first ionization constant is pK_a1 = 1.2 and the second ionizatio. This why the equation should be: CaC 2 O 4 --> Ca 2+ + C 2 O 42- Upvote 2 Downvote Comments 2 Report Mark P. THANK YOU!!!!! H2C2O4 (oxalic acid) and KHC2O4 (potassium hydrogen oxalate) b.

Conclusion The dissociation equation for the given species, , emphasizing on its behavior as Arrhenius acid is given below as, . The compound parts into its segment particles. A weak acid undergoes 2.0% dissociation. What is the Ka expression for nitrous acid? Given the fact that #K_(a1)< H2^+ + SO4^{2-}}$$, My question is, why can't the dissociation reaction happen like this: Is H2C2O4 an acid, a base, or a salt? In the future, you should try to find a better way of critiquing than a downvote and a reprimand.
