CHEMICAL REACTION EXPERIMENTS AT HOME:

CHEMICAL REACTION EXPERIMENTS AT HOME BALOON INFLATION EXPERIMENT At, PSLE Science Tuition in Singapore

Discussion points:

Discussion points Materials Experimental procedure Experiment Results Scientific explanation

Materials:

Materials plastic   bottle. 150 ml of hot  water. Yeast. Sugar. Balloon. Tea spoon .

Experimental Procedure:

Experimental Procedure Pour three tea spoons of dry yeast and two tea­spoons of sugar into a  bottle . Slowly pour hot water into the  bottle . Put the balloon over the bottle and wait for half an hour.

Experimental Result:

Experimental Result The liquid starts to foam, and the  balloon   inflates .

Scientific Explanation:

Scientific Explanation Yeast is a microscopic fungus that consumes sugar and releases carbon dioxide . The numerous bubbles of this gas rise to the surface , causing the liquid to foam and the balloon to inflate . In chemistry , this process is called fermentation . This particular chemical reaction involves the release of ethyl alcohol and carbon   dioxide

Chemical Formula:

Chemical Formula С₆Н₁₂О₆ → 2С₂Н₅ОН + 2СО₂

Fermentation:
