Blood cells do not shrink in blood because blood is
1 hypotonic
2 isotonic
3 equimolar
4 hypertonic
Explanation:
Two solutions of different substances having same osmotic pressure at same temperature are known as isotonic solutions. Blood cells do not shrink in blood because blood is isotonic. When a cell is placed in a solution having an isotonic pressure equal to its own, the cell maintains its normal volume. As isotonic solution has the same osmotic pressure as the cells contained in it, there is no concentration gradient.

At certain temperature a $5.12 \%$ solution of cane sugar is isotonic with a $0.9 \%$ solution of an unknown solute. The molar mass of solute is;
1 60
2 46.17
3 120
4 90
5 92.34
Explanation:
Molar mass of solute $=\frac{342}{5.12}=\frac{\mathrm{X}}{0.9} \Rightarrow 60.117$

Isotonic solutions have same
1 temperature
2 vapour pressure
3 freezing point
4 osmotic pressure
Explanation:
When two solutions have same osmotic pressure and salt concentration are said to be isotonic solution. Iso (same) and tonic (concentration).

Red blood cells are placed in a solution and neither haemolysis nor crenation occurs. Therefore, the solution is
1 hypertonic
2 hypotonic
3 isotonic
4 isotopic
Explanation:
When red blood cells are placed in a solution and neither haemolysis nor erenation occurs. This means that solution is isotonic in nature, since in isotonic solution, there is no process of osmosis takes place.
