The pH of a solution can be calculated using the formula:

pH = -log[H+]

where [H+] is the concentration of hydrogen ions in the solution. To find the pH when given the hydroxide ion concentration, we need to use the fact that:

[H+][OH-] = 1x10^-14

where [OH-] is the concentration of hydroxide ions in the solution.

Rearranging this equation to solve for [H+], we get:

[H+] = 1x10^-14 / [OH-]

Plugging in the given hydroxide ion concentration, we get:

[H+] = 1x10^-14 / 4.8x10^-8

[H+] = 2.083x10^-7

Now, we can find the pH using the formula above:

pH = -log[H+]

pH = -log(2.083x10^-7)

pH ≈ 6.68

Therefore, the pH of the solution is 6.68.
