Answer:
Aim: To compare the rate of evaporation of water, acetone and diethyl ether.
Materials required: China dish, Pipette, Beaker, Weighing balance Measuring flask, Acetone, Distilled water, Diethyl ether, Watch
PROCEDURE:
1. Take three china dishes.
2. Pipette out 10 ml of each sample.
3. Dish A-Acetone Dish B-Water Dish C-Diethyl ether
4. Record the weights before beginning the experiment.
5. Leave the three dishes undisturbed for ½ an hr and wait patiently.
6. Record the weights of the samples after the given time.
7. Compare the prior and present observations.
OBSERVATION: Water (gm) Acetone (gm) Diethyl Ether (gm) Weight of dish 50 50 50 Weight of (dish + substance) before evaporation 60 57.85 57 Weight of (dish + substance) after evaporation 59.8 55.55 54.33 Weight of substance evaporated 0.2 2.30 2.67
Inference and conclusion: - The rate of evaporation of the given three liquids is in order :- Diethyl Ether>Acetone>Water
Reason: - Water has extensive hydrogen bonding in between oxygen atom of one molecule and hydrogen atom of another molecule. But this is absent in the case of acetone.
