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 some time 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.
