Question

Define curdling.

Answer 1

Curdling - It is the process by which a liquid transforms into a semisolid mass.

Example -

• Curdling of milk occurs by adding lime juice or vinegar to the milk.
• The curd which is formed consists of different compositions as compared to the milk.
• The new substance formed can not be converted back into milk.
• Therefore, curdling of milk to form curd is desirable, irreversible, and endothermic.
