A solution of 0.211 M NaOH is used to titrate 24.0 mL of a H2SO4 solution. If 19.0 mL of the NaOH solution is required to reach the endpoint, what is the molarity of the H2SO4 solution?

H2SO4(aq)+2NaOH(aq)→2H2O(l)+NaSO4(aq)

1 answer

mols NaOH = M x L = ?
Look at the equation. mols H2SO4 = 1/2 mols NaOH
Then M H2SO4 = mols H2SO4/L H2SO4.
