At certain temperature the K(w) of D(2),...

At certain temperature the `K_(w)` of `D_(2)`,O is `10^(=-16)` M. Then the pD of pure `D_(2)`,O at that temperature is

A

7

B

16

C

8

D

6

Text Solution

Verified by Experts

The correct Answer is:
C
` K_w " of " D_2O =10 ^(-16) , [D^(+) ] [OD^(-)] = 10 ^(-16) `
` [D^(+) ]= 10^(-8) M rArr P^(D) = 8`
