Explanation:</h3>
To answer the question we need to ask ourselves several questions
What is pH?
- pH refers to the measure of alkalinity or acidity of a substance.
How is pH measured?
- pH is measured by determining the concentration of Hydrogen ions (H⁺) in a given solution.
- Then calculated by getting negative logarithm of hydrogen ions concentration.
- That is, pH = -log[H⁺]
What does pH tell about a solution?
- A solution with a pH below 7 is acidic while a solution with a pH above 7 is basic while that with a pH of 7 is neutral.
- A pH of 1 to 3 represents a strong acid while a pH of 4 to 6 represents a weak acid.
- Strong alkali or bases have a pH of 12 to 14 while weak alkali or bases have a pH of 8 to 11.
- Therefore, a solution with a pH of 14 is a very strong base
