What volume of 0.1 m h2so4 solution is needed to neutralize 40 ml of 0.2 m naoh solution?

Answered by admin @ 16/08/2021

Hey dear,

● Answer -
40 ml of 0.1 m H2SO4

● Explaination -
NaOH dissociates as -
NaOH --> Na+ + OH-

Hence, it will produce
[OH] = 0.2 × 40 / 1000 moles
[OH] = 8×10^-3 moles

So We'll need same amount of H+ ions to neutralize it.

H2SO4 dissociates as -
H2SO4 --> 2H+ + (SO4)2-

Hence, it will produce
[H+] = 2 × 0.1 × x / 1000
8×10^-3 = 2 × 0.1 × x / 1000
x = 40 ml

Therefore, 40 ml of 0.1 m H2SO4 will be required.

Hope this helps you...
