Why is sugar and vinegar a chemical change?
The difference between chemical and physical changes is that chemical change is when a new substance is formed, and the reaction is irreversible. So as salt and vinegar do not react, it is indeed a physical change.
Is reacting with vinegar a physical or chemical property?
Reacting with vinegar is a chemical property because it involves a chemical change where new substances are formed. The reaction between vinegar (acetic acid) and another substance causes a chemical reaction that alters the composition of the original substances.
Is Reactivity to vinegar is an example of physical property?
Yes, reactivity to vinegar is an example of a physical property because it describes how a substance behaves without altering its chemical composition. In this case, the reaction between vinegar and a substance demonstrates a physical change rather than a chemical one.
Why phenopthalein and milk of magnesia pink in colour?
Phenolphthalein turns pink due to its acidic pH, particularly in the presence of an acid. Milk of magnesia, which contains magnesium hydroxide, can turn pink when exposed to air due to slow oxidation of magnesium ions. This pink color change is not indicative of any chemical reaction or specific property of milk of magnesia.
Is baking soda reacting with vinegar a physical or chemical change?

What happens when you put an antacid tablet to the vinegar?
When you put an antacid tablet into vinegar, a chemical reaction occurs between the bicarbonate compounds in the antacid and the acetic acid in the vinegar. This reaction produces carbon dioxide gas, which creates bubbles and fizzing as the gas escapes. The reaction results in a neutralization process, reducing the acidity of the vinegar. Overall, you observe effervescence and a change in the solution's pH.
What change is it when Some white powder from your kitchen fizzes when you put it into vinegar?
This is a description of the reaction between the acetic acid, which is the "active ingredient" in vinegar, and baking soda, which is sodium bicarbonate. This double replacement reaction is covered in another question on WikiAnswers.

Is reactivity with vinegar chemical or physical change?
Reactivity with vinegar is a chemical change because it involves a rearrangement of atoms and the formation of new substances. The reaction between vinegar (acetic acid) and a metal, for example, produces hydrogen gas and a salt (metal acetate), which are different substances than the original ones.
