The solution ranked with the presence of hydronium ion concentration from higher to lower is pH = 1.05 > [OH⁻] = 4.35 * 10 ⁻² > [H₃O⁺] = 3.16 * 10⁻⁴ M > pOH = 7 > pOH = 4.
What is pH and pOH?
The pH and pOH can be given as the logarithmic value of the presence of hydrogen or hydronium and hydroxide ion concentration in a solution respectively.
The hydronium ion concentration can be given as:
[H₃O⁺] = antilog (-pH)
- The hydronium ion concentration of pH = 1.05 is:
[H₃O⁺] = 10⁻¹.⁰⁵
[H₃O⁺] = 0.089 M
The pH from pOH can be calculated as:
pH = 14 - pOH
- pH of solution with pOH 7 is:
pH = 14 - 7
pH = 7
The hydronium ion concentration can be given as:
[H₃O⁺] = 10⁻⁷
[H₃O⁺] = 1 * 10⁻⁷ M
- The pH of solution with pOH 4 isL:
pH = 14 - 4
pH = 10
The hydronium ion concentration can be given as:
[H₃O⁺] = 10⁻¹⁰
[H₃O⁺] = 1 * 10⁻¹⁰ M
Thus, the solutions from highest to lowest hydronium ion concentration can be ranked as:
pH = 1.05 > [OH⁻] = 4.35 * 10 ⁻² > [H₃O⁺] = 3.16 * 10⁻⁴ M > pOH = 7 > pOH = 4.
