Question

A student measured the pH values of four solutions marked A, B, C and D and found them to be 6, 12, 2 and 14 respectively. The solution which is likely to be strongly acidic is (1) A
(2) B
(3) C
(4) D

Answer 1

A student measured the pH values of four solutions marked A, B, C and D and found them to be 6, 12, 2 and 14 respectively. The solution which is likely to be strongly acidic is C.

Explanation:

The acid will be lower the pH value, the higher the strongest acid, then, will be solution C.

Strongest acid:-  

• A strongest acid has a greater acidity than pure sulphuric acid.

• Fluoroantimonic acid is the most potent strongest acid in the world.

• Fluoroantimonic acid is a combination of fluorofluoric acid and pentafluoride antimony.

Therefore the correct answer is Option(3) C.
