(a) a clear and homogenous solution was formed (b) A pink and clear solution was formed
(c) water formed a separate layer on the top of water (d) the acid formed a separate layer on the top of water

Answer 1

Acetic acid is soluble in water . therefore it will mix with water and form a homogeneous .hence option (a) is correct.

Answer 2

When 2ml of acetic acid was added in drops to 5ml of water, it was noticed that a clear and homogeneous solution was formed.

Explanation:

• When acetic acid is dissolved in water, it gets dissociated into $H^+$ ions and $CH_3COO^-$ ions.
• The chemical equation involved in the reaction is as follows:

$CH_3COOH+H_2O\rightarrow H^+ + CH_3COO^-$

• Due to the formation of a high amount of $H^+$ ions, the acid gets more chance to bond with water.
• Due to such type of bond, high interaction between water and acetic acid occurs.
• As the rate of interaction is more, the rate of solubility is more due to which it forms a clear homogeneous mixture.
• This the correct observation related to the given scenario is inferred to option (a).
