Question

How much water should be added to 500 ml of N/2 NaOH solution to obtain a decinormal solution?

Answer 1

Answer:

I think quantity of water will be 300ml

Answer 2

The amount of water that should be added to 500 ml of N/2 NaOH solution to obtain a decinormal solution isequal to 2000 mL.

• The number of gram equivalent of NaOH in the solution before addition of water and after addition of water will remain constant.
• So, N1.V1 = N2.V2, where V2 is the final total volume of the solution.
• Therefore V2 = N1.V1/N2 = 0.5*500/0.1 = 2500 mL.
• Hence the volume of water that needs to be added is equal to 2000ml (2500-500).
