Question

Give scientific reasons for the curdling of milk is a chemical change .

Answer 1

Chemical change: It is a permanent change in which an entirely new substance is formed with different properties. It is a permanent and irreversible change in which the original substance loses its own composition and properties.

• The formation of curd from milk is a chemical change.
• Curd taste, physical state, and composition are different from milk and cannot be converted back into milk.
• Hence it is a chemical change.
