Answers
Answer:-
Experiment to observe changes during combustion of sugar:
This experiment will helps to you..!!
Aim: To observe changes during combustion of sugar
Apparatus: Wooden stand, test tubes, rubber stopper, delivery tube, glucose powder, lime water, spirit lamp.
Procedure:
1)Take a small amount of glucose in a small test tube
2)Arrange the apparatus
3)Heat the test tube until the glucose catches fire
Observations:
1)In the initial stage the glucose becomes liquid
2)Later it turns to black color after catching fire
3)In this process carbon dioxide and water are produced
4)Energy is released as heat
5)The carbon dioxide released changes lime water to milky white
Conclusion:
1)From this experiment, we can conclude that carbon dioxide, water and heat are produced during combustion of glucose in the laboratory
2)The carbon dioxide changes lime water to milky white in nature.
Aim: To observe changes during combustion of sugar.
Apparatus: Wooden stand, test tubes, rubber stopper, delivery tube, glucose or sucrose powder, lime water.
Procedure: Take a small test tube and add a little amount of glucose to it.
Arrange the apparatus as shown in the figure.
Heat the test tube with a Bunsen burner.
Heat until the glucose catches fire.
Observation: When glucose in the test tube starts burning, you will observe that carbon dioxide and water are produced and energy is released as heat.
Glucose is burnt at high temperature so that it liberates energy.
Once the glucose burns, we cannot stop the process easily.
When water is added to the burning sugar, the combustion stops.
The carbon dioxide released in this process changes lime water to milky white.
Inference: From this experiment, we can conclude that during combustion of glucose in the laboratory, carbon dioxide, water and heat are produced.
The carbon dioxide produced changes lime water to milky white in nature.
