Question

How does the size of blood cells change when placed in an aqueous solution containing less than 0.9% (m/v) sodium chloride

Answer 1

Answer:

0.9 percent nacl is isotonic for blood cells..but if kept in a medium less than this value it will swell because it is hypotonic..cells become more rounded

Answer 2

The size of the blood cells swells and bursts out when placed in an aqueous solution containing less than 0.9% sodium chloride.

• When blood cells are placed in a solution containing less than 0.9% of NaCl, the water content enters the blood cells.
• The water enters through the plasma and then enters through the wall of the blood cells leading it to swell.
• The above process takes place because blood cells are isotonic in nature with 0.9% NaCl.
