Activity Description:

Observe reaction of Vinegar with Baking soda in Changes around Us - Class 7 Science Experiment

The experiment involves combining vinegar (acetic acid) with baking soda (sodium bicarbonate) to observe the production of carbon dioxide gas. The gas is then passed through limewater to identify the formation of calcium carbonate and water.

Required Items:

Vinegar (acetic acid), baking soda (sodium bicarbonate), test tube, limewater (calcium hydroxide).

Step by Step Procedure:

  1. Set up the apparatus as shown in Fig-8.
  2. Take a teaspoon of vinegar (or lemon juice) in a test tube.
  3. Add a pinch of baking soda to the test tube containing the vinegar.
  4. Observe the reaction as bubbles are produced with a hissing sound.
  5. Pass the gas produced (carbon dioxide) through freshly prepared limewater.

Experiment Observations:

  1. The limewater changes to a milky white color, indicating the presence of carbon dioxide. Chemical reactions: Vinegar + Baking Soda -> Carbon dioxide + other substance; Carbon dioxide + Lime water -> Calcium Carbonate + Water.

Precautions:

Handle the materials with care, and ensure proper ventilation while conducting the experiment.

Lesson Learnt from Experiment:

The experiment illustrates a chemical change, as new substances (carbon dioxide and calcium carbonate) are formed during the reaction.
