Is souring milk an example of a chemical change?
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.
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.
Is milk souring a physical change?
It is not physical but rather chemical: milk sugar (lactose) is converted to lactic acid by Lactobacillus bacteria.
How does pH affect milk?
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.
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.
