Question

Varun’s mother added plenty of salt to the mango pickle she made. This is to:

1. enhance the colour of the pickle.
2. inhibit the growth of microorganisms.
3. increase the nutritional value.
4. create a hypertonic solution.

Options

• A and C

• B and C

• C and D

• B and D

Answer 1

B and D

Explanation:

• Adding excess salt creates a hypertonic solution around the pickle.
• This causes water to move out of microorganisms by osmosis, leading to their dehydration.
• As a result, the growth of microorganisms is inhibited, preserving the pickle.
