QUESTION

# What happens when you mix baking soda and vinegar? Would it be a chemical or physical reaction? A) it flows out of the top, it is physical B) it does not show any difference, physical C) the mixture flows out, chemical D) none of the above Do great!

The answer is C.

When baking soda and vinegar are mixed together, a chemical reaction occurs. This is a vigorous reaction. Baking soda is called sodium bicarbonate, and has the chemical formula "NaHCO"_3" Vinegar is a very dilute solution of acetic acid with the formula "CH"_3"COOH".

The word equation for the overall reaction is:

Solid sodium bicarbonate reacts with aqueous acetic acid to produce aqueous sodium acetate ("CH"_3"COONa"), liquid water, and carbon dioxide gas.

The chemical equation for the overall reaction is:

"NaHCO"_3("s")+"CH"_3"COOH(aq)"rarr"CH"_3"COONa(aq)"+"H"_2"O(l)"+"CO"_2("g")"
