1. The amount of OH¯ present in the solution is 0.1 mol/L

2. The amount of H⁺ present in the solution is 0.0000000000001 mol/L

3. The pH of the solution with H⁺ concentration of 1×10⁻⁴ mol/L is 4

1. How to determine the amount of OH¯ in the solution

We'll begin by obtaining the pOH of the solution

  • pH = 13
  • pOH =?

pH + pOH = 14

13 + pOH = 14

Collect like terms

pOH = 14 - 13

pOH = 1

Finally, we can determine the OH¯

  • pOH = 1
  • OH¯ =?

pOH = –Log [OH¯]

1 = –Log [OH¯]

Multiply through by –1

–1 = Log [OH¯]

Take the anti-log of –1

[OH¯] = anti-log of (–1)

[OH¯] = 0.1 mol/L

2. How to determine the amount of H⁺

  • pH = 13
  • H⁺ =?

pH = –Log [H⁺]

13 = –Log [OH¯]

Multiply through by –1

–13 = Log [H⁺]

Take the anti-log of –13

[H⁺] = anti-log of (–13)

[H⁺] = 0.0000000000001 mol/L

3. How to determine the pH

  • H⁺ = 1×10⁻⁴ mol/L
  • pH =?

pH = –Log [H⁺]

pH = –Log 1×10⁻⁴

pH = 4
