Question

What is the pH of a solution with [H+] = 1.25 mc015-1.jpg 10–10 M?

Answer 1

[ H+]=10-pH
it become
[H+]=0.1

Answer 2

Answer : The pH of a solution is, 9.903

Explanation : Given,

Concentration of hydrogen ion =
`1.25* 10^(-10)M`

pH : It is defined as the negative logarithm of hydrogen ion concentration.

Formula used :

`pH=-\log [H^+]`

Now put the value of hydrogen ion concentration in this formula, we get the pH of a solution.

`pH=-\log (1.25* 10^(-10))`

`pH=9.903`

Therefore, the pH of a solution is, 9.903
