A solution tested in the laboratory shows a pH of 14. Which of the following statements best describes this solution?

A. It is a highly acidic solution with a high hydrogen ion concentration.
B. It is a highly alkaline solution with a high hydrogen ion concentration.
C. It is a highly basic solution with a high hydrogen ion concentration.

Answer (3)

pH 1 - 6 = Acids pH 7 = Neutral pH 8 - 14 = Bases
An alkaline is a base that is very soluble in water.
Since we know the solution has a ph of 14, it cannot be A, since A is an acid. It can however be B or C. I'd say that the most logical answer would be B , because no testing has been done for other alkaline properties.

B...the higher the pH, the more basic...this rules out the solution being acid and an alkali is defined as a soluble base, as you're testing a solution we know it is a soluble base.

A solution with a pH of 14 is highly basic, meaning it has a low concentration of hydrogen ions. Among the provided options, B is the closest, although both B and C incorrectly imply a high hydrogen ion concentration. Thus, while the solution is alkaline, it also has low hydrogen ion concentration, rendering the statements somewhat inaccurate.
