Can someone tell me how to do this question?

Question

How many liters of a .2 M NaOH solution are required to completely react with 1.00 L of a 0.100 M solution of H2SO4 to produce sodium sulphate and water?

i know the answer, but how do i go about doing this question? thanks

Answer 1

You need to know the normality of the solutions, the amount of hydrogen ions and hydroxide ions produced.
.2 M NaOH produces .2 M (OH)-
.1 M H2SO4 produces .2 M (H)+ (2 for each molecule)
Therefore it becomes a 1:1 ratio so for 1 liter of H2SO4 you would need 1 Liter of NaOH to neutralize it.
