A student adds 2 mL of acetic acid to a test tube containing 2 mL of distilled water. He then shakes the test tube well and leaves it to settle for some time. After about 5 minutes he observes that in the test tube there is: (A) a clear transparent colourless solution (B) a clear transparent pink solution (C) a precipitate settling at the bottom of the test tube (D) a layer of water the layer of acetic acid



Acetic acid dissolves completely in distilled water and gives a clear, colourless and transparent solution. Hence, the correct option is A.
