Question

In an experiment to study the properties of ethanoic acid, a student takes about 3 ml of ethanoic acid in a dry test tube. He adds are equal amount of distilled water to it and shakes the test tube well. After sometime he is likely to observe that; A. a colloid is formed in the test tube.; B. The ethanoic acid dissolves readily in water.; C. The solution becomes light orange.; D. Water floats over the surface of ethanoic acid.(All India - 2014)

Answer 1

Answer:

B. The etanoic acid dissolves readily in the water

Explanation:

1. Etanoic acid is soluble in water in all the proportion

Answer 2

The student will observe that the ethanoic acid dissolves readily in water.

Given:

• 3 ml of ethanol is reacted 3 ml of water.

To find:

Observation for the reaction between ethanol and water.

Explanation:

• The concept involved in this scenario is the properties of ethanoic acid. The following are the major properties of ethanoic acid ($CH_3COOH$).

1. It is a compound that belongs to the carboxylic acid group and is acidic.
2. It has a strong pungent odor.
3. It is readily dis-solvable in water in any proportions.
4. It changes the color of blue litmus to red.

• As per the given scenario, the student is mixing an equal amount of ethanoic acid with water.
• The chemical reaction involved in this reaction is as follows:

$CH_3COOH+H_2O$⇄ $H^++CH_3COO^-$

Conclusion:

• As per the properties of ethanoic acid, it readily gets dissolved in water, it is inferred that option B is the correct observation for the given experiment.
