Question

Calculate the ph of sweater which has a hydrogen ion concentration of 1 times 10 to the power of 8

Answer 1

The pH of the sweater containing Hydrogen ion concentration

`[H^(+)]=1* 10^(-8)` is

8

Step-by-step explanation:

pH = It is the negative logarithm of activity (concentration) of hydrogen ions.

pH = -log([H+])

Now, In the question the concentration of [H+] ions is :

`[H^(+)]=1* 10^(-8)`

`pH = -log(1* 10^(-8))`

use the relation:

`log(10^(-a))=a`

`pH= -(-8)`

pH = 8

Note : 1 times 10 to the power of 8 must be" 1 times 10 to the power of -8"

If the concentration is

`[H^(+)]=1* 10^(8)`

Then pH = -8 , which is not possible . So in that case the pH calculation is by other method
