It is a chemical reaction. Baking soda contains carbonate ions, which react with hydrogen ions from the acetic acid in vinegar according to the ionic equation:
CO3-2 + 2 H+ -> CO2 + H2O. CO2 is a gas at standard temperature and pressure. CO2 formation causes the fizzing, as the gas escapes from the other product and the still unreacted baking soda and vinegar.
====================================================
Well, you completely deleted my very simple and responsive answer and made it a little more complicated.
As I said in my first response, this is a chemical reaction involving the combination of an acid and a base. When an acid and base combine, the reaction easily moves forward forming a salt. This is a chemical reaction. I should have also added that the byproducts were also included water and CO2 and perhaps some unreacted original products depending upon the amount of each supplied.
Along the lines of your response a more complete response would be:
CH3COOH + Na(HCO3) -> H2O + NaOCOCH3 + CO2
vinegar is mostly a weak acetic acid - CH3COOH and water.
baking soda is essentially - Na(HCO3)
The sodium precipitate on the right side is the residue I was speaking of. It is by definition, a salt.
(You shouldn't have erased my answer because it wasn't wrong and completely responsive to the question. I rather doubt the person making the query wanted to know THAT much about it. Now you want to balance this equation for everyone?)
Yes
No, it is a chemical change. A chemical reaction occurs when the two are mixed-- bubbling/fizzing.
Baking Soda and Vinegar combinedmake a fizzing reaction when the Acetic acid in the vinegar reacts with Sodium Bicarbonate (baking soda).
Yes this is a chemical reaction The fizzing is Carbon Dioxide being generated as the baking soda reacts with the vinegar.

To create a chemical reaction using baking powder and vinegar, simply mix the two together. The baking powder (sodium bicarbonate) reacts with the vinegar (acetic acid) to produce carbon dioxide gas, which causes bubbling and fizzing. This reaction is commonly used in baking to make cakes and breads rise.
The vinegar-baking soda reaction is a chemical change.
Yes, if you put vinegar in powder and it fizzes, that indicates a chemical reaction is occurring. The fizzing is typically caused by the reaction between the acetic acid in the vinegar and a basic substance in the powder, such as baking soda (sodium bicarbonate). This reaction produces carbon dioxide gas, which creates the fizzing effect.
Sugar will not fizz in vinegar on the other hand if baking soda is added fizzing / gassing/ and bubbling will occur ( which is a evidence of a chemical change ) Sugar will not fizz in vinegar on the other hand if baking soda is added fizzing / gassing/ and bubbling will occur ( which is a evidence of a chemical change )
