how many H- ions can one molecule of NaOH produce?

Question

How many H+ ions can one molecule of citric acid produce?

How many does this affect the titration of citric acid with NaOH?

Answer 1

Citric acid is a tri-protic acid.  That means it has 3 acidic hydrogens.  So, one molecule of citric acid will produce 3 H⁺ ions.

NaOH, as pointed out by Arturo, will not produce any H⁺ ions because it has no hydrogens to donate.

The titration of citric acid with NaOH is a straightforward acid/base titration requiring 3 moles of NaOH for each 1 mole of citric acid.  The products of the titration are water and sodium citrate in the ratio of 3 : 1
