The pH of a solution is the negative logarithm (base 10) of the hydrogen ion concentration. This relationship can be expressed with the following formula:

pH = -log[H+]

Where: pH is the pH of the solution, [H+] is the hydrogen ion concentration in the solution.

To find the hydrogen ion concentration when the pH is given, you can rearrange this formula to solve for [H+]:

[H+] = 10^-pH

So, if the pH of the solution is 4.5, the hydrogen ion concentration would be:

[H+] = 10^-4.5

Therefore, the hydrogen ion concentration of the solution is 3.2 × 10^-5 M. So, the correct answer is A.3.2 × 10^-5 M.
