If you place blood cells in a solution containing more than 0.9% (mass/volume) sodium chloride, water will flow out of the cells and they will shrink. Such a solution is called
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Hypertonic
A solution containing more than 0.9% (m/v) sodium chloride causes water to flow out of blood cells and makes them shrink; such a solution is called a hypertonic solution.
Reasoning:
When the surrounding solution has a higher solute concentration than the cell (hypertonic), water moves out of the cell by osmosis, leading to shrinkage (crenation).
