Fizzing and Foaming
We want to find out which liquids are acid,we know that when we combine baking soda with vinegar we get a fizzing and foaming reaction. Our teacher told us that baking soda is a carbonate and vinegar is an acid.
lemon juice - fizz
tomato - juice nothing
milk - foam
water - nothing
tea - nothing
grape - foam
What we need
What we will do
The lemon juice did fizz with the baking soda, the tomato foamed a little, the grape juice foamed, the tea did nothing and so did the milk and water.
What Farah, Manish, Aryan and me found out is that when you mix all of them together after they were mixed they don’t fizz or foam.
Baking soda, also known as bicarbonate of soda, is a chemical compound made of sodium, hydrogen, carbon and oxygen. It is an alkaline substance that is similar to a salt and it reacts to acidic substances, including most liquids. The reaction gives off carbon dioxide gas. It exists naturally in bile and neutralizes stomach acids. Baking soda is often used in baking, personal cleansers and science projects because of its ability to react chemically with acids.
