Question

If 25.00 ml of H2SO4 solution is titrated to an end point with 32.16 ml of 0.1986 M NaOH, what is the molarity(M) of the H2SO4 acid?

Answer 1

H2SO4 + 2NaOH ==> Na2SO4 + 2H2O

mols NaOH = M x L = ?
Convert mols NaOH to mols H2SO4 using the coefficients in the balanced equation.
Finally, M H2SO4 = mols H2SO4/L H2SO4.
