when milk curs it is a chemical change. A physical change is change in form, which is revesrable. Like water being frozen then thawed. A chemical change is irreversible, and involves a change in the chemical make up. What is happening is a new compound is being formed by the milk reacting with the air and such.

Is curdling of milk physical or chemical?

The curdling of milk is a chemical process. It occurs when proteins in the milk, such as casein, interact with an acid (like lemon juice or vinegar), causing the proteins to denature and clump together, forming curds. This process is irreversible and results in a change in the composition of the milk.


Why is melting of butter is reversible whereas curdling of milk is irreversible?

Melting is a phase change, which is entirely controlled by temperature (pressure is also relevant but under normal circumstances, air pressure is approximately constant). Curdling is a chemical change. The process that leads to a particular chemical is much more complicated than a change in temperature.

What is chemical equation of milk curdling?

The chemical equation for milk curdling involves the coagulation of proteins in milk by the action of acid, such as lactic acid produced by bacteria. This process causes the proteins in milk, mainly casein, to denature and clump together to form curds, which separates from the whey. The reaction can be summarized as: casein + acid -> curdled milk (curds) + whey.

Chemical formula of curdling of milk?

The chemical reaction responsible for curdling milk involves the denaturation of protein, primarily casein, by an acid like lemon juice or vinegar. This denaturation causes the proteins to unfold and stick together, forming curds. The chemical equation is complex and involves various molecules and ions, but the key reaction involves the breakdown of the protein structure due to the acid.
