Solution A Solution B

Oxygen concentration (mg/ml)

100 50
PO2 (mmHg) 50 100

All else being equal, which solution is more likely to have a higher osmolarity?

All else being equal, which solution is more likely to have a warmer temperature?

Which solution is most like blood?

Which solution has the higher oxygen solubility?

If solutions A and B were separated by a gas permeable membrane (like gill epithelium), what direction will oxygen diffuse?

Homework Answers

Answer #1

1. Osmolarity that means an absolute measure of the concentration of solute in a solution .Considering above two solutions, solution A will have a higher osmolarity than solution B.

2. The warmer water contains less dissolved oxygen means to say solution B will have a warmer temperature.

3.solution B is most like blood.The range of normal PO2 for blood is 75-100 mmHg.If it is less than this, it means blood is not getting enough oxygen.

4.Solution B has the higher oxygen solubility, as we know that the solubility of the gases increases with the increase in pressere.
