​

Answer 1

Answer:

D: When the acidity of a solution increases, the pH increases.

Explanation:

It is totally wrong to assert that when the acidity of a solution increases, the pH of the solution will increase

The right answer is that when the acidity of a solution increases, the pH value decreases.

• The pH scale records the level of acidity and basicity of a substance.
• It runs from 1 to 14
• From 7 to 14 signifies increasing basicity
• As the acidity of a substance increases, the pH value reduces.
• For acids 1 is the highest acidity levels.
