Answer: The pH of the solution is 1.34

Explanation:

pH is defined as negative logarithm of hydrogen ion or hydronium ion concentration. It is basically defined as the power of hydrogen ions in a solution.

The equation used to calculate pH of the solution is:

[tex]pH=-\log[H^+][/tex]

We are given:

[tex][H^+]=4.5\times 10^{-2}M[/tex]

Putting values in above equation, we get:

[tex]pH=-\log(4.5\times 10^{-2})[/tex]

[tex]pH=1.34[/tex]

Hence, the pH of the solution is 1.34
