The number of `H^(o+)` ions present in 1mL of solution having, pH=13 is

A

`6.02 xx 10^(10)`

B

`6.02 xx 10^(7)`

C

`6.02 xx 10^(13)`

D

`10^(13)`

Text Solution

Verified by Experts

The correct Answer is:
B
`pH = 13 " " therefore [H^(o+)] = 10^(13)M = 10^(-13)` mol `(1000 mL)^(-1) = (10^(-13))/(1000) = 10^(-16) "mol mL"^(-1)`
Number of `[H^(o+)] = 10^(-16) xx 6.023 xx 10^(23) = 6.023 xx 10^(7)` ions
