When the protein in the milk called casein comes in contact with the vinegar the casein and vinegar do not mix but rather the molecules move around and join forces to make the casein plastic. Baking soda is a basic compound called sodium bicarbonate while vinegar is a diluted solution that contains acetic acid 95 water 5 acetic acid.

A substance called Casein forms. When vinegar is added to baking soda gas is produced. Milk curdles when mixed with vinegar because the acid from the vinegar causes the protein molecules in milk to come together to form visible solidsThe solids float in the clear whey forming curdled milk.

Normally the protein molecules inside milk are folded up. How Could You Cause A Chemical Change To Vinegar. This is evidence of a chemical change because the gas is a new substance.

So as salt and vinegar do not react it is indeed. Normally the protein molecules in milk repel each other. The precipitate is nothing but denatured casein protein.

Changes of state are defined as physical changes for example liquid water and ice frozen water are both the same substance water even in a liquid or solid from the chemical composition remains the same. A chemical reaction takes place when the egg is placed in vinegar. In this activity the milk is heated and then mixed with the white vinegar or lemon juice which is an acid.

When milk and vinegar are mixed it causes a chemical change that can be seen by the curdling milk. When you mix baking soda and vinegar is it a physical or chemical change.
