Question

Which of the followingequations represents the proper net ionic equation for the completeneutralization reaction between the weak acidH2CO3 (aq) and the strong base, LiOH(aq)?

A-H2CO3 (aq) + 2 LiOH (aq) ----> 2H2O (l) + Li2CO3 (aq)
B -CO32- (aq) + 2 Li+ (aq) ---->Li2CO3 (aq)
C -H2CO3 (aq) + 2 OH- (aq) ----> 2H2O (l) + CO32- (aq)
D - H2+ (aq) +2 OH- (aq) ----> 2 H2O (l)
E - H+ (aq) +OH- (aq) ----> H2O (l)
F - 2 H+ (aq) +LiOH (aq) ----> 2 H2O (l) + Li+(aq)
G - 2 H+ (aq) +Li+. (aq) ----> HLi (aq)
H -CO32- (aq) + OH- (aq) ---->HCO4 (aq)

How do I solve these and the like?

Explanation / Answer

Answer C Because H2CO3 is weak acid, it doesn't dissociatecompletely. Notice it has 2H in acid=>diss. 2 times H2CO3(aq) + OH-(aq)-->HCO3- + H2O(l) HCO3-(aq) + OH-(aq) -->CO32-(aq) + H2O(l) ------------------------------------------------------------- =>H2CO3(aq) + 2OH-(aq)--> CO32-(aq) +2H2O(l)
