Which two terms describe the ph scale

pH scale is a device used to measure the concentration of Hydrogen ions (H+) in the solution.

Explanation:

pH scale measurement ranges from 0 to 14 and most arrangements do fall inside this range, in spite of the fact that it's conceivable to get a pH beneath 0 or over 14.

Of which 0 to 6.9 is acidic , 7 is neutral , and 7.1 to 14 is basic. Anything underneath 7.0 is acidic, and anything above 7.0 is basic, or essential.

So By using ph scale the acidic and basic nature of the solution can be measured.

So the terms used are acidity and basicity.
