Question

what volume of water should be added to 50ml m/5hcl solution to make it decimolar.​

Answer 1

Answer:

Volume of deci normal Solution= 50 ml. Concentration of decinormal Solution=0.1N Volume of centi normal Solution= V concentration of centinormal Solution=0.01

So V x 0.01 = 50 x 0.1

Therefore V = 50 x 0.1/0.01= 500 ml.

So the amount of water to be added to 50 ml.of deci normal Solution

= (500- 50)= 450 ml.
