Is baking soda and vinegar combined a chemical change?
When you combine them it is a chemical reaction (change) yes, but them combined in a solution is a physical 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 ) 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 )
Yes, chemical changes can cause bubbling, which is a gas release occurring because of a chemical reaction. This reaction occurs because the two reactants have differing pH. Vinegar is an acid, and baking soda is a base. Nuetralization is occurring, which results in a different substance, another sign of a chemical change.
If you add baking soda and vinegar then you have made something new-different so it is a chemical change?
In a chemical change, you produce a substance(s) that you did not have before, with a completely different chemical composition. For example, when you combine vinegar and baking soda, a reaction occurs, and when that reaction is completed, you no longer have vinegar or baking soda. You have new substances composed of a rearrangement of the atoms of the stuff you had before. Evidence of a chemical change can include, but is not limited to…
