If maleic acid could be represented as H2Ma, write the 2 equations for its reaction with NaOH in the space below (showing the sequential neutralization of each acidic proton):
1) H2Ma + NaOH --> H3O + MaNa (molecular)
2) H2Ma + OH- --> H2O + MaH- (net ionic)
Note: the "-" is the superscript.
1) H2Ma + NaOH --> H2O + NaHMa
2) NaHMa + NaOH --> H2O + Na2Ma
I think is what they are after so you end up with the disodium salt.
