What is the limiting reactant if 2.047 grams of NaOH (s) reacts with 101.3 mL of a 2.09 M HCl solution?

Expert Solution

Molar mass of NaOH = At.mass of Na + At.mass of O + At.mass of H

= 23+16+1

= 40 g/mol

Given mass of NaOH , m = 2.047 g

So number of moles of NaOH , n = mass/molar mass

= 2.047 / 40

= 0.0512 moles

Number of moles of HCl , n' = Molarity x volume in L

= 2.09 M x 0.1013 L

= 0.212 moles

The balanced equation is : HCl + NaOH ---> NaCl + H2O

According to the balanced equation ,

1 mole of NaOH reacts with 1 mole of HCl

0.0512 mole of NaOH reacts with 0.0512 moles of HCl

So (0.212 - 0.0512 ) moles of HCl left unreacted so HCl is the excess reactant.

Since all the mass of NaOH completly reacted , NaOH is the limiting reactant.

To determine which is the limiting reactant, we compare the ratio of moles of each reactant to the ratio of their coefficients in the balanced equation. Why do we base our choice of which substance is limiting, based on the number of initial moles, and not on its initial mass in grams?
