Why does the typical base indicator exhibit its color change over a range of about 2 PH units?
The usual range of the color change on the indicator is between 1.5-2 pH units because of the sensitivity of the indicators. The universal indicator is used in most test.
What are substances which exhibit a specific color in the presence of acid or base?

What happens if phenolphthalein was added to salts?
If phenolphthalein is added to a solution of salts, it will not undergo any specific reaction. Phenolphthalein is used as an indicator in acid-base titrations, where it changes color depending on the pH of the solution. Since salts do not have acidic or basic properties, phenolphthalein will not exhibit any color change.
