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:
A
`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
