a 23ml H2SO4 solution is titrated by 50 ml 0.10 M NaOH solution, what is the molarity of H2SO4 solution? (Note that H2SO4 is a diprotic acid)
H2SO4 + 2NaOH ==> Na2SO4 + 2H2O
moles NaOH used = M x L = ??
Convert moles NaOH to moles H2SO4 using the coefficients in the balanced equation. 1 mol NaOH = 1/2 mol H2SO4.
M H2SO4 = moles H2SO4/L H2SO4.
