Answer:

A. It is a very strong base.

Step-by-step explanation:

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
