Question

phenolphthalein when added to a liquid X didn't show any colour change. Mention two inferences drawn from this activity​

Answer 1

Answer:

The two inferences drawn from this activity are:

1. The liquid X may be an acidic solution.

2. The liquid X may have reached the equivalence point and is under neutral conditions.

Explanation:

Phenolphthalein solution turns pink when added to a solution that is basic in nature because it undergoes deprotonation in the basic medium that imparts the pink colour to the solution.

Answer 2

Answer:

The solution could either be acidic or it could be neutral.

Explanation:

This is because Phenolphthalein remains colourless in acidic and neutral solutions whereas it turns magenta in basic solutions
