Question

The volume of water which must be added to 40 mL of a 0.25 N H2SO4.
solution in order to make an exact decinormal solution is
(1) 60 ml (b) 20 ml (c) 50 mL (d) 25 ml
​

Answer 1

Answer:

Explanation:

When a solution is diluted or two solutions of different substances react then V1N1=V2N2

Volume of water added is= V2-V1

Now let's find V1

0.1V1=0.25*40

V1=100ml

Therefore volume of water added is V2-V1

100-40=60ml
