Can the beautiful rainbow come into being a bubble ?
what kind of scientific principle and knowledge for this mysterious phenomenon contains, Alpha science classroom science experiment for kids topic is DIY produce magic rainbow of the bubble with children together to use baking soda and vinegar together, this experiment helps children to understand the simple knowledge of chemistry, and become the most severe rainbow maker.
Alpha science classroom：DIY rainbow bubble experiment principle
Baking soda and vinegar react because one is a base and the other is an acid.
Baking soda is an alkaline compound called sodium bicarbonate.
Vinegar is a dilute solution containing acetic acid.
The reaction between baking soda and vinegar is actually two separate reactions.
The first reaction is an acid-base reaction.
When the vinegar and baking soda are first mixed together, the hydrogen ions in the vinegar react with the sodium and bicarbonate ions in the baking soda.
The result of this initial reaction was two new chemicals: carbonic acid and sodium acetate.
The second reaction is the decomposition reaction.
Carbonic acid is formed as a result of the first reaction and immediately begins to decompose into water and carbon dioxide gas.
Like carbon dioxide in the bubbles of a carbonated drink, the carbon dioxide (which is formed as carbonic acid breaks down) rises to the top of the mixture.
Bubbles and foams form when baking soda and vinegar are mixed.
Kids, what could be better than a bubbling rainbow?
