Citric acid (abbreviated H3Cit) is a triprotic acid, so 3 moles of hydroxide ions are required per mole of citric acid for complete neutralization. A.) Write the balanced chemical equation for the reaction of citric acid with sodium hydroxide. (Note that citrate ion is actually a polyatomic ion with carbon, hydrogen, and oxygen atoms and an overall charge of −3. For now, express citrate ion as Cit3−.) B.) If 36.10 mL of 0.223 M NaOH is used to neutralize a 0.515 g sample of citric acid, what is the molar mass (in g/mol) of the acid?
