Analytical Chemistry Question 228
Question: How many ml of 1 (M) $ H_2SO_4 $ is required to neutralise 10 ml of 1(M) $ NaOH $ solution
[MP PET 1997; MP PMT 1999]
Options:
A) 2.5
B) 5.0
C) 10.0
D) 20.0
Show Answer
Answer:
Correct Answer: B
Solution:
1M H2SO4 = 2N $ H_2SO_4 $
$ \overset{H_2SO_4}{\mathop{N_1V_1}}\ =\ \overset{NaOH}{\mathop{N_2V_2}} $ 2 × V1 = 10 × 1, $ V_1\ =\ \frac{10\ \times \ 1}{2}\ =\ 5\ ml $
