What is the equation when ethanedioic acid is neutralised by sodium hydroxide? How is it balanced?

There are two carboxylic acid groups in ethanedioic acid (COOH)2. So 1 mol of the acid reacts with 2 mol NaOH (assuming that you add enough alkali to neutralise all the acid).
 
The organic product is (COONa)2.

You must have these approved by those in authority in your school or college laboratory. Do not rely on what is said on this website. For further guidance see our tutorial on Risk Assessment.
