Question

What is the pH of a solution where the [H+] is 1.0 x 10-11?

Answer 1

Answer:

The correct answer of this question is $log = 11$

Explanation:

Given -  The pH of a solution where the [H+] is 1.0 x $10^{-11}$

To Find - What is the pH of a solution.

The concentration of hydrogen ions in a solution is measured by its pH, which is a measure of its acidity. Pure water splits into hydrogen and hydroxyl (OH) ions in roughly equal amounts.$H^{+} =$ 1  × $10^{-11}$$mol/dm^{3}$

$pH = -log(H^{+})$

$pH = - log ( 1$ × $10^{-11}$)

$pH = (-log 1)$ + ( - log $-log10^{-11}$ )

$pH = - 0 -$ $log$ $10^{-11}$

$pH = - log 10^{-11}$

$pH = -(-11) log10$

$pH = 11(1)$

$pH = 11$
