∙ 12y agoSouring 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.
Yes, souring milk is an example of a chemical change. The breakdown of lactose by bacteria into lactic acid changes the composition of the milk, resulting in a new substance with different properties.
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.
It is not physical but rather chemical: milk sugar (lactose) is converted to lactic acid by Lactobacillus bacteria.
pH affects milk by determining its acidity level. Changes in pH can impact the taste, texture, and overall quality of milk. For example, a lower pH can lead to souring or curdling of milk, while a higher pH can affect its shelf life and safety.
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.
making regular milk.
Souring, as in Souring milk," Mom! This Milk Is Souring!" YUCK!!! ==Gee, sour milk...?== Now that's a "rousing" thought...
souring is the property of milk

The souring and curdling of milk is caused by bacteria.
The spoilage of milk is sometimes called souring.
nothing.
the pH of milk would be lower, or more acidic
cheese

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.
