CHEMICAL REACTION EXPERIMENTS AT HOME BALOON INFLATION EXPERIMENT At, PSLE Science Tuition in Singapore
Discussion points • Materials • Experimental procedure • Experiment Results • Scientific explanation
Materials • plasticbottle. • 150 ml of hot water. • Yeast. • Sugar. • Balloon. • Tea spoon.
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 The liquid starts to foam, and the ballooninflates.
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 carbondioxide
Chemical Formula С₆Н₁₂О₆ → 2С₂Н₅ОН + 2СО₂
