Milk turning sour is a chemical change. It occurs due to the fermentation of milk sugars by bacteria, leading to the production of lactic acid, which changes the taste and smell of the milk.
No, milk turning sour is a chemical change because the bacteria in the milk interact with the lactose to produce lactic acid, changing the composition of the milk.
Yes, milk turning sour is a chemical change. This is because the bacteria present in the milk ferment the lactose sugars, producing lactic acid which changes the chemical composition of the milk, resulting in the sour taste and smell.
During summers, milk can turn sour due to a chemical change called souring. This is caused by the growth of bacteria in the milk, which metabolize the lactose (milk sugar) into lactic acid. The lactic acid decreases the pH of the milk, giving it a sour taste and causing the proteins to denature.
No, it's a chemical property
the sour milk stank
as the bcteria chaanges the ph to an acid thus turning the milk sour thereby changing the ph value.

Sour milk is milk that is off. You drink, you get diarrhoea. So don't drink sour milk.
Any milk can go sour.
Acts a bit like preservative would. it makes milk a bit alkaline so as to reduce the pace of bacteria acting on it ,as they add acids (e.g. lactic acid) to the milk and turn it sour. this keeps the milk from becoming sour for a long time.
No Your right sour milk can never be too sour for an recipe.. I agree with you on that one.
