(Answered) Determine the hydronium ion concentration

Academics

1. A solution has a pH of 0.17. Determine the hydronium ion concentration.

2. A solution of perchloric acid has a concentration of 3.00 × 10-4 mol/L. Determine the pH of the solution.

3. A solution has a pOH of 4.5. Determine the hydroxide ion concentration.

4. A solution of strontium hydroxide has a concentration of 8 × 10-2 mol/L. Determine the pOH of this solution.
Hint: Write a dissociation equation first, use that to help determine the concentration of hydroxide ions.

5. Compare the magnitude of the hydroxide ion concentration of a solution that has a pOH of 2.65 with that of a second solution that has a pOH of 4.65.
