Osmosis (13.3.4)

Question 1

• Osmotic pressure is related to concentration by Π = M•R•T.

Answer 1

• Osmotic pressure is related to concentration by Π = M•R•T.

Question 2

• The osmotic pressure at the membrane is equal to density times gravity times height (d•g•h), thus Π = M•R•T = d•g•h.

Answer 2

• The osmotic pressure at the membrane is equal to density times gravity times height (d•g•h), thus Π = M•R•T = d•g•h.

Question 3

• Osmotic pressure is the most sensitive colligative property.

Answer 3

• Osmotic pressure is the most sensitive colligative property.

Question 4

• The osmotic pressure generated by the sugar solution in a maple tree is able to raise sap to a height of about 25 meters.

Answer 4

• The osmotic pressure generated by the sugar solution in a maple tree is able to raise sap to a height of about 25 meters.
