Question
Which of the following has the highest value of pH?
- Citric acid
- KOH
- Lemon juice
- Water
Hint:
KOH has the highest value of pH which is from 10 to 13.
The correct answer is: KOH
- Strong bases, such as KOH, separate into their constituent ions when dissolved in water.
- Although potassium hydroxide (KOH) has an exceptionally high pH (normal solutions typically range from 10 to 13), the precise value depends on how much of this power base is present in the solution.
