Answer: The pH of the solution is 1.49

Explanation:

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

To calculate the pH of the reaction, we use the equation:

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

where,

[tex][H^+]=3.26\times 10^{-2}M[/tex]

Putting values in above equation, we get:

[tex]pH=-\log(3.26\times 10^{-2})\\\\pH=1.49[/tex]

Hence, the pH of the solution is 1.49
