Question on: JAMB Chemistry - 2004
What volume of 0.5 mol dm-3 H2SO4 will exactly neutralize 20cm3 of 0.1 mol dm-3 NaOH solution?
A
2.0 cm3
B
5.0 cm3
C
6.8 cm3
D
8.3 cm3
Ask EduPadi AI for a detailed answer
Correct Option: A
2NaOH + H2SO4 → Na2SO4 + 2H2O
CaVa/CbVb = ratio of acid/ratio of base
(0.5 * Va)/(0.1 * 20) = 1/2
∴ Va = 2.0cm
