Reaction: Vinegar and Baking Soda.
Properties of the Original Substances: A clear liquid (Vinegar) and a white powder (Baking Soda).
Properties of Products: The combination bubbles and foams.
This reaction involves an acid-base reaction between vinegar (acetic acid) and baking soda (sodium bicarbonate). When they are mixed together, carbon dioxide gas is produced, which causes the bubbling and foaming that is observed.
The reaction can be represented by the following equation:
Acetic acid + Sodium bicarbonate -> Sodium acetate + Water + Carbon dioxide
Overall, this chemical reaction is exothermic, meaning it releases heat. It is a common reaction used in various household cleaning or baking purposes. The bubbling and foaming action can be useful for removing stubborn stains or as a leavening agent in baking recipes.

Reaction: Vinegar and Baking Soda.
Properties of the Original Substances: A clear liquid (Vinegar) and a white powder (Baking Soda).
Properties of Products: The combination bubbles and foams.
This is a chemical reaction. There are a few reasons to support this statement.
Firstly, a chemical reaction involves the formation of new substances with different properties from the original substances. In this case, when vinegar and baking soda are combined, carbon dioxide gas is produced, along with other products like water and sodium acetate. The formation of these new substances indicates a chemical change has taken place.
Secondly, the bubbling and foaming observed during the reaction is an indication of a gas being produced. This production of gas is a characteristic feature of a chemical reaction.
Overall, the change in properties of the substances involved and the evident production of gas support the conclusion that the reaction between vinegar and baking soda is a chemical reaction.
When vinegar and baking soda are mixed together, a chemical reaction occurs. Vinegar is an acidic substance, while baking soda is a basic substance. The reaction between the two produces carbon dioxide gas, water, and a type of salt called sodium acetate.
Here is a step-by-step explanation of what happens:
1. Initially, the vinegar and baking soda are in their original states: vinegar is a clear liquid, and baking soda is a white powder.
2. When the two substances are combined, the acid in the vinegar (acetic acid) reacts with the base in the baking soda (sodium bicarbonate).
3. The reaction releases carbon dioxide gas as a byproduct. This gas is responsible for the bubbling and foaming that you observe when vinegar and baking soda are mixed.
4. The release of carbon dioxide gas also causes pressure to build up inside the mixture.
5. As the pressure increases, the gas bubbles expand and rise to the surface, carrying some of the liquid along with it. This is why you see the foaming action.
6. The reaction will continue until all the baking soda or vinegar is used up. At this point, the foaming will stop, and you will be left with a solution that contains water, sodium acetate, and any remaining unreacted vinegar or baking soda.
It's important to note that the reaction between vinegar and baking soda is an example of an acid-base reaction, and the products formed differ from the original substances.
