Question

Calculate the pH of a solution with [H+]= 1 x 10^-11

11
3
13
14

Answer 1

11 by -log concentration of H+

Answer 2

Answer: Option (a) is the correct answer.

Step-by-step explanation:

pH is the negative logarithm of concentration of hydrogen ion.

That is, pH = -log
`[H^+]`

Hence, pH of solution with
`[H^+] = 1 * 10^(-11)` is calculated as follows.

pH = -log
`[H^+]`

= -log
`(1 * 10^-{11})`

= 11

Therefore, pH of solution with
`[H^+] = 1 * 10^(-11)` is 11.
