∙ 9y agoSour milk is a chemical change because it cannot return back to regular milk. It contains bacteria an will continue to change.

∙ 11y agoit is a chemical change firstly it cant be reversed secondly action of bacteria causes to change its chemical composition and thirdly little amount of invisible energy is also released

Souring of milk is an example of a?
Chemical Change.
Which of the following involves a chemical change combinding an acid and a base dew forming or souring milk?
Souring milk! (Heh, I hate section reviews!)
What is a physical change Milk becomes sour an iron nail rusts?
Both milk souring and iron rusting are chemical changes.
Why Milk souring is a physical change?
It is not physical but rather chemical: milk sugar (lactose) is converted to lactic acid by Lactobacillus bacteria.

Is souring a milk a chemical reaction?
yes See Is Sour Milk a physical or chemical change for more info
Why is churning a chemical change?
Souring milk causes a chemical change because it changes its state of matter (from a liquid to a semi-solid), and it grows bacteria. When milk sours it causes a permanent change, therefore making it a chemical change.
Is milk sours a physical or chemical change?

Is souring milk a physical or chemical change Why or why not?
It's a chemical change. The smell is the giveaway; a smell that wasn't there before is often an indicator of a chemical change. Also, the rate at which the milk sours can be changed by heat. For example, milk in the refrigerator is actually undergoing this souring reaction at all times, but the lower temperature inside the refrigerator slows it down so that it takes many days. But if you leave it outside the refrigerator, it will sour much more quickly - in a matter of hours. An increase in heat, therefore, quickens the reaction rate. This would not be the case in a physical change.

Is souring milk an example of a chemical change?
Yes it is a chemical reaction between the calcium and the oxygen [i may be wrong their] but the rate of reaction is very slow.
