Description
"Changes of Baking Soda and White Vinegar" Changes of Substances PPT Courseware 3
Characteristics of baking soda: small white crystals
Characteristics of white vinegar: colorless liquid with a sour smell
discuss:
A. How should we do this experiment? Please design your own solution.
B. How to mix and what is the quantity to mix?
In this experiment, the ratio of baking soda and white vinegar must be controlled well, otherwise it will cause a lot of waste. Then take a glass, pour three spoons of vinegar, and then carefully pour in a spoonful of baking soda. Cover it with a piece of glass and record the phenomenon in the box of P33.
What happens when baking soda and white vinegar are mixed
Bubbles bubbled, gas was produced, and the glass became cold.
What gas is produced when baking soda and white vinegar are mixed? Next we will do two experiments
1. Insert burning thin strips of wood into the cup.
2. Pour the gas in the glass onto the candle flame. (Be careful not to pour out the liquid in the glass)
Through the above experiment, what characteristics can we know about this gas?
Can extinguish a burning flame and is heavier than air.
do you know?
Although our experiments cannot prove what gas is produced, scientists have determined after extensive research that this gas is carbon dioxide, which is a component of air. Carbon dioxide does not support combustion and is heavier than air. The bubbles in soda drinks are carbon dioxide. The gas we exhale when we breathe also contains carbon dioxide, and carbon dioxide gas is also produced when burning candles.
Observe the liquid in the glass. Is the baking soda still there? Is the remaining liquid still white vinegar? What substance do you think is left behind? Please collect after class.
