In a experiment to study the properties of ethanoic acid, a student takes about 3 mL of ethanoic acid in a dry test tube. He adds an equal amount of distilled water to it and shakes the test tube well. After sometime he is likely to observe that
- a colloid is formed in the test tube.
- the ethanoic acid dissolves readily in water.
- the solution becomes light range
- water floats over the surface of ethanoic acid.
