How much water should be added to 200 cc of semi-normal solution of NaOH to make it exactly decinormal

A

200cc

B

400cc

C

800cc

D

600cc

Text Solution

Verified by Experts

The correct Answer is:
C
using `N_1V_1 = N_2V_2`
` 1/2 xx 200 = 1/10 xx V_2 `
where `V_2 = 1000 ` cc
volume of water added = 100-200-800cc
