1. Phosphoric acid reacts with sodium hydroxide according to the equation: H3PO4 + 3NaOH --> Na3PO4 + 3H2O
ns
If 1.75mol H3PO4 is made to react with 5.00mol NaOH, identify the limiting reactant

NaOH

Explanation:

The limiting reactant is the reactant in short supply in an experiment.

We have been given:

 Number of moles of H₃PO₄   = 1.75mle

Now from the balanced reaction equation:

         1 mole of H₃PO₄ will require 3 moles of NaOH to react with

         1.75 mole of H₃PO₄ will then require 1.75 x 3  = 5.25mole of NaOH

But the given amount of NaOH is 5mole, so NaOH is the limiting reactant.
