Why Milk souring is a physical change?
When milk sours, it undergoes a chemical change rather than a physical change. The bacteria in the milk ferment the lactose sugar into lactic acid, changing the chemical composition of the milk. This process cannot be reversed by physical means, distinguishing it as a chemical change.
Is souring milk a physical or chemical change Why or why not?
Souring milk is a chemical change because it involves the breakdown of lactose (a sugar in milk) into lactic acid by bacteria present in the milk. This process changes the composition and properties of the milk, leading to the sour taste and thicker consistency associated with spoiled milk.
Which of the following involves a chemical change combinding an acid and a base dew forming or souring milk?
Souring milk involves a chemical change where lactic acid is produced by the fermentation of lactose in milk by bacteria. This is not the result of combining an acid and a base, but rather the conversion of lactose (a sugar) into lactic acid.
What is a physical change Milk becomes sour an iron nail rusts?
A physical change refers to a change in appearance or state that does not alter the chemical composition of the substance. When milk sours, it undergoes a physical change because its appearance and taste change, but the molecules remain the same. Similarly, when an iron nail rusts, it is a physical change because the iron's appearance changes as it forms rust, but the chemical composition of the iron is not altered.
Souring of milk is an example of a?
Souring of milk is an example of a fermentation process. This occurs when bacteria in the milk convert lactose (milk sugar) into lactic acid, causing the milk to thicken and develop a tangy flavor. This process is commonly used to create products like yogurt and cheese.

No, milk souring is an example of a chemical change. When milk sours, bacteria ferment the lactose in the milk, producing lactic acid, which changes the composition and properties of the milk. This is a chemical reaction, not a physical change.

Is milk souring a chemical or physical change or both?
Well just to start off nothing can ever be a physical and chemical change it has to be one or the other.. and the best way to know which one it is is a physical change doesnt change the substance and a chemical change will change the substance into something else. So milk going sour would be chemical because it isnt regular milk anymore its sour milk. but if it was something like evaporating water then it would be physical because its still water its just in the gas state. -Hope that helps(:
What is Milk going sour is physical or chemical?
Chemical. If anyone wants to put more detail, please do.
