Question

Does fizzing always indicate the occurrence of a chemical change? Explain why or why not?

Answer 1

Is opening a beer bottle a physical or chemical change?

Answer 2

Well, I'm sure there's something besides chemicals that reacts to acid, but there's calcite... You know, it's in rocks, and so MOSTLY chemicals, but some other stuff; I'm just not sure what it is. =] Sorry if that was kinda confusing

Answer 3

Fizzing indicates the formation of a gas which indicates a chemical change but it does not necessarily mean a chemical change has occurred, it's only an indication.

Answer 4

Fizzing is not a very scientific term!

Although always is very strong and fizzing is vague, I would say yes.

If you mix a carbonate with an acid, it will fizz and release carbon dioxide, which is a chemical change.  Even opening a bottle of pop is a chemical change.  The carbonated water (notice the carbonate) is reacting with the phosphoric acid (notice the ingredients in soda) and it is releasing CO2.

Note that boiling is not a chemical change (but I feel boiling and fizzing are different).

Answer 5

The so called fizzing is a chemical reaction of either carbon dioxide gas (for sodas) or a catalyst added to the mixture. The primary material does not change its properties.
