How much water should be added to 200 c.c of seminormal solution of NaOH to make it exactly decinormal?

A

(a)`200 c c`

B

(b)`400 c c`

C

(c )`800 c c`

D

(d)`600 c c`

Text Solution

Verified by Experts

The correct Answer is:
d
`N_(1)V_(1)=N_(2)V_(2), 1/2xx200=1/10xxV_(2),V_(2)=1000 mL`
Volume of water added `=1000-200=800 mL`
