Some Basic Concepts Of Chemistry Question 235
Question: 5 ml of N HCl, 20 ml of $ N/2H _2SO _4 $ and 30 ml of $ N/3HNO _3 $ are mixed together and volume made to one litre. The normality of the resulting solution is [MNR 1991]
Options:
A) $ N/5 $
B) $ N/10 $
C) $ N/20 $
D) $ N/40 $
Show Answer
Answer:
Correct Answer: D
Solution:
$ NV=N _1V _1+N _2V _2+N _3V _3 $
$ N\times 1000=1\times 5+\frac{1}{2}\times 20+\frac{1}{3}\times $ 30 $ =5+10+10=25 $
$ N=0.025=\frac{N}{40} $ .
