Question

The hydrogen ion​ concentration, ​[H+​], in a certain cleaning compound is left bracket Upper H Superscript plus Baseline right bracket equals 3.6 times 10 Superscript negative 11H+=3.6×10−11. Use the formula pH=−log[H+] to find the pH of the cleaning compound.

Answer 1

Answer: The pH of the cleaning compound is 10.44

Explanation:

pH is defined as the negative logarithm of hydrogen or hydronium ion concentration that are present in a solution.

The equation representing pH of the solution follows:

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

We are given:

$[H^+]=3.6\times 10^{-11}$

Putting values in above equation, we get:

$pH=-\log(3.6\times 10^{-11})$

$pH=10.44$

Hence, the pH of the cleaning compound is 10.44
