Question

When preserved in a strong salt solution, a raw mango's size decreases significantly. Which of the ensuing procedures best explains this?

• A. Diffusion
• B. Osmosis
• C. Reverse Osmosis
• D. Dialysis

Answer 1

The correct option is B

Osmosis

The explanation for the correct answer:

B. Osmosis

Osmosis:

• Osmosis is the process by which solvent molecules move from a low concentration solution to a high concentration solution through a semi-permeable membrane.
• When placed in a strong salt solution, a raw mango shrinks and loses water.
• Osmosis is the name of this phenomenon.
• Solvent molecules move from a less concentrated solution to a more concentrated one through a semipermeable barrier in this process.

The explanation for incorrect options:

A. Diffusion:

• Diffusion is the movement of molecules along a concentration gradient from a region of greater concentration to a region of lower concentration.

C. Reverse osmosis:

• Reverse osmosis is a unique form of filtration that removes bigger molecules or pollutants from water by passing them through a semi-permeable, porous membrane.

D. Dialysis:

• Dialysis is a synthetic method of removing extra fluid and waste from the body.

Hence, the correct answer is option B, osmosis.
