Which one of the following is a chemical change?

Options

  1. ADissolving sugar in water
  2. BMelting of ice
  3. CCrystallization
  4. DMilk turning sour

Correct answer

D. Milk turning sour

Step-by-step solution

Milk turning sour is an example of chemical change as there is a change in chemical composition of milk in which lactose sugar of milk changes to lactic acid. Dissolution of sugar in water melting of ice and crystallization are the physical changes.
