Answer:

[H3O+] = 1.0*10^-12 M

[OH-] = 0.01 M

Explanation:

We can use the following equation to find the hydronium ion concentration.  Plug in the pH and solve for H3O+.

pH = -log[H3O+]

[H3O+] = 1.0*10^-12 M

Now, to find the hydroxide ion concentration we will use the two following equations.

14 = pH + pOH

pOH = -log[OH-]

14 = 12 + pOH

pOH = 2

2 = -log[OH-]

[OH-] = 0.01 M

Based on the data provided, the hydroxide ion concentration of the solution is 1 * 10⁻² M.

What is pH and pOH of a solution?

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

pOH is defined as the negative logarithm of the hydroxide ion concentration of a solution.

pH of a solution and pOH of a solution are related by the formula:

  • pH + pOH = 14

pOH = 14 - pH

Thus pOH of the solution = 14 - 12

pOH = 2

From definition, pOH = - log [OH⁻]

[OH⁻] = 10^⁻pOH

[OH⁻] = 10⁻²

[OH⁻] = 1 * 10⁻² M

Therefore, the hydroxide ion concentration of the solution is 1 * 10⁻² M.
