1/12/2024 OSMOSIS & HENRY'S LAW

Question 1

In general, does the solubility of salts increase or decrease with temperature?

Answer 1

Increase

Question 2

for gasses, solubility DECREASES with temperature

Answer 2

ex: OXYGEN (happy and sad fish)

Question 3

How do you calculate gas solubility?

Answer 3

Henry’s Law

Question 4

What is osmosis?

Answer 4

The result of SOLVENT diffusion

Question 5

What is meant by an “Isotonic” condition?

Answer 5

Concentration is the same on the inside and outside of the membrane

Question 6

What happens when you take a cell and put it into saltwater?

Answer 6

Hypertonic condition: higher solute concentration outside the cell

Question 7

If blood is diluted, would red blood cells be hypertonic, isotonic or hypotonic?

Answer 7

HYPOTONIC (water would diffuse at a greater rate into the cell than out)

Question 8

What is Osmotic Pressure?

Answer 8

Solvent movement generates osmotic pressure (II)

II depends on the amount of particles in solution, not the identity of those solutes

• Colligative: the magnitude depends on

Question 9

what is a non-electrolyte?

Answer 9

something that doesn’t dissociate

Question 10

Why are the theoretical i values different from the experimental values?

Answer 10

Because the theoretical i assumes no attraction between hydrated ions after separated
