Question

phenolphthalein when added to a liquid X did not show any colour change. Mention 2 inferences drawn from this activity

Answer 1

Answer:

Explanation:

1) liquid x is an acid.

2)liquid x turns blue litmus paper to red.

3)liquid x is sour in taste.

Answer 2

$\large\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R}}}}$

The two inferences drawn from this activity are:

1. $\dashrightarrow$The liquid X may be an acidic solution.

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

$\tt\large{\blue{Explanation}}$

$\dashrightarrow$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.
