pH and Its Properties Quiz

What is the formula for calculating pH?

• pH = -log [H⁺]

• pH = [H⁺][OH⁻]

• pH = [H⁺] + [OH⁻]

• pH = [H⁺] / [OH⁻]

What is the relationship between pH and pOH?

• pH + pOH = 14

• pH + pOH = 7

• pH + pOH = 10

• pH + pOH = 0

If the pH is 5, what is the nature of the solution?

• Acidic

• Neutral

• Basic

• None of the above
