Determine how many milliliters of 0.102M NaOH solution is needed to neutralize 35.0mL of 0.125M H2 SO4 solution.

2 answers

2NaOH + H2SO4 ==> Na2SO4 + 2H2O

moles H2SO4 = M x L = 0.125 x 0.035L = ??.
moles NaOH (look at the coefficients in the balanced equation) = 2 x moles H2SO4.
Finally, M = moles/L. Solve for L and convert to mL.
85.8ml
