What appearance of an acidic analyte solution containing phenolphthalein indicates the endpoint of titration with a basic solution?

When the solution becomes colorless

Explanation:

phenolphthalein in a base gives a purple colour. As the acid is introduced, the purple color begins to fade away. The end point of the reaction is attained when the solution becomes colorless.

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.
