Concept explainers
(a)
Interpretation:
If the pH value represents an acidic, basic, or neutral solution should be identified.
Concept Introduction:
The pH defines the acidity of a substance. Acids have pH value less than 7 and bases have pH more than 7. Also, higher the acidity lower will be the pH value. A neutral solution contains equal concentration of an acid and a base therefore, the pH is 7.
(b)
Interpretation:
If the pH value represents an acidic, basic, or neutral solution should be identified.
