Final answer:

The pH of the solution is 4.34. The pOH of the solution is 9.66. The hydroxide ion concentration is 2.98 x 10^(-10) M.

Step-by-step explanation:

The pH of a solution can be calculated using the formula pH = -log[H3O+]. In this case, the [H3O+] is given as 4.6 x 10-5 M. Plugging in this value into the formula, we get: pH = -log(4.6 x 10-5)

= 4.34.

Therefore, the pH of the solution is 4.34.

The pOH of a solution can be calculated using the formula pOH = -log[OH-].

However, the [OH-] concentration is not given in this question.

To find the pOH, we can use the fact that pH + pOH = 14.

Thus, pOH = 14 - pH

= 14 - 4.34

= 9.66.

Therefore, the pOH of the solution is 9.66.

The hydroxide ion concentration can be calculated using the formula [OH-] = 10^(-pOH).

Plugging in the value of pOH from the previous step, we get: [OH-] = 10^(-9.66)

= 2.98 x 10^(-10) M.

Therefore, the hydroxide ion concentration is 2.98 x 10^(-10) M.
