Question

How many ml of 1.0 M NaOH solution are needed to neutralize 100 ml of 2.0 M H2SO4 solution

Answer 1

First you must the balanced equation.
2NaOH+H2SO4 → 2H2O+Na2SO4

From this you can see that it takes 2 moles NaOH per 1 mole H2SO4. Moles H2SO4 = 2.0 mol/L x 0.1 L = 0.2 moles.

Moles NaOH needed = 2 x 0.2 = 0.4 molesVolume NaOH = (x L)(1.0 mol/L) = 0.4 molesx = 0.4 liters = 400 ml NaOH
