1. The pH is 2.44

2. The pOH is 3.36

3. The pH is 13.24

4. The pOH is 11.64

5. The pH is 11.99

1. How to determine the pH

  • Hydrogen ion concentration [H⁺] = 3.6×10¯³ mol/L
  • pH =?

pH = –Log H⁺

pH = –Log 3.6×10¯³

pH = 2.44

2. How to determine the pOH

  • Hydroxide ion concentration [OH¯] = 4.4×10¯⁴ mol/L
  • pOH =?

pOH = –Log OH¯

pOH = –Log 4.4×10¯⁴

pOH = 3.36

3. How to determine the pH

  • Hydrogen ion concentration [H⁺] = 5.7×10¯¹⁴ mol/L
  • pH =?

pH = –Log H⁺

pH = –Log 5.7×10¯¹⁴

pH = 13.24

4. How to determine the pOH

  • Hydroxide ion concentration [OH¯] = 2.3×10¯¹² mol/L
  • pOH =?

pOH = –Log OH¯

pOH = –Log 2.3×10¯¹²

pOH = 11.64

5. How to determine the pH

We'll begin by obtaining the pOH of the solution. This illustrated below:

  • Hydroxide ion concentration [OH¯] = 9.7×10¯³ mol/L
  • pOH =?

pOH = –Log OH¯

pOH = –Log 9.7×10¯³

pOH = 2.01

Finally, we shall determine the pH as follow:

  • pOH = 2.01
  • pH =?

pH + pOH = 14

pH + 2.01 = 14

Collect like terms

pH = 14 - 2.01

pH = 11.99
