How much water is needed to dilute 10 mL of 10 N hydrochloric acid to make it exactly decinormal (0.1 N)?

A

990 mL

B

1000 mL

C

1010 mL

D

100 mL

Text Solution

Verified by Experts

The correct Answer is:
A
`N_1V_1 = N_2V_2implies 10 xx 10 = 0.1 xx V_2`
`V_2 = 100/0.1 =1000`
Thus water to be added = 1000 – 10 = 990 ML
