h2c4h4o4 + 2naoh --> 2h2o + na2c4h4o4

as for the previous question im sorry i forgot to plug the maleic acid in the formula properly. so this ones it ^

.2213 of c4h4o4 used (maleic acid)
and
.1 M NaOH

1. show the equation for 1st and 2nd ionization
2. find molecular mass of maleic acid

help? How do I do this?

I have a list of V (mL) and pH values...
basically titrated 50 mL

1 answer

of 0.1 M NaOH with 0.2213 M maleic acid

1. First Ionization: H2C4H4O4 + 2NaOH → 2H2O + Na2C4H4O4
Second Ionization: Na2C4H4O4 + 2NaOH → 2NaOH + Na2C4H4O4

2. The molecular mass of maleic acid is 116.07 g/mol.
