Question

b
ACTIVITY 3
(To be demonstrated by the teacher)
You will need vinegar, baking soda, lime water, test tubes, stoppers and a delivery
tube.
Use a graduated cylinder to measure 10 ml of vinegar and pour it in a conical flask.
Place a thermometer in the vinegar. Read the thermometer and record the temperature
on the activity sheet. While the thermometer is in the cup, add 1/2 teaspoon of baking
soda. Pass the gas evolved through lime water via the delivery tube. Watch the
thermometer to observe any change in temperature. Is there a temperature change
when the reaction takes place?
Carbon dioxide gas is given off in the reaction between vinegar and baking soda. The
rising bubbles confirm the release of the carbon dioxide gas. This gas when passed
through lime water, it turns milky. This is due to the formation of calcium carbonate.
Since the reaction between vinegar and baking soda results in the formation of a new
substance, it is a chemical change.
This chemical change can be represented by the following equation:
Vinegar + Baking soda → Carbon dioxide + Water +Other substances...can someone give me the aim of this above​
