6. Complete the following table: SOLUTE NaCl Urea CaCl₂ CaCl₂ MOLARITY (mole/L) 3 0.2 OSMOLARITY (osmol/L) 4 0.3 EXPLANATION TONICITY represents the ability of a solution to change the shape or turgidity of cells by altering their internal water volume (= the ability of a solution to grab water from the cells). Every cell, including the red-blood cell, contains within the boundary of its cell membrane a certain number of non-penetrating solute particles (0.3 osmol/L) which will not diffuse out of th cell.

6. Complete the following table: SOLUTE NaCl Urea CaCl₂ CaCl₂ MOLARITY (mole/L) 3 0.2 7. Explain the following terms: Fill in the blanks. Solution A is iso-osmotic to red-blood cells TONICITY represents the ability of a solution to change the shape or turgidity of cells by altering their internal water volume (= the ability of a solution to grab water from the cells). Solution A is hyper-osmotic to red-blood cells Every cell, including the red-blood cell, contains within the boundary of its cell membrane a certain number of non-penetrating solute particles (0.3 osmol/L) which will not diffuse out of the cell. Solution A is hypo-osmotic to red-blood cells OSMOLARITY (osmol/L) 4 Solution A is isotonic to red-blood cells Solution A is hypertonic to red-blood cells Solution A is hypotonic to red-blood cells 0.3 EXPLANATION Solution A has a higher concentration of osmotically active solute particles than the red- blood cells (osmolarity of the solution A is higher than the osmolarity of red-blood cells) Solution A has a lower concentration of osmotically active solute particles than the red- blood cells (osmolarity of the solution A is lower than the osmolarity of red-blood cells) Water is drawn out of the cell by this solution and the red-blood cells shrink or crenate. Water moves into the red-blood cells, the cell volume increases and cells can even burst. 1-blood cells rupture it is called hemolysis. 8. Make sure you understand the following mechanisms: Hemolysis of red-blood cells: The cells are ruptured.
