solubility and diffusion

Question 1

Henry’s law

Answer 1

amount of gas dissolved in a liquid is directly proportional to the partial pressure of the gas in equilibrium with the liquid. used in hyperbaric oxygen therapy

Question 2

Graham’s law

Answer 2

rate of diffusion of gas inversely proportional to square root of its molecular weight

Question 3

blood gas solubility coefficient

Answer 3

measure of solubility of substance in blood vs its solubility in air. If low, partial pressure in blood rises quickly so faster effect at CNS

Question 4

oil gas solubility coefficient

Answer 4

measure of gas solubility in lipid vs air. Determines lipid solubility. If not very lipid soluble less stored in adipose tissue so offset quicker

Question 5

Bunsen solubility coefficint

Answer 5

voluem of gas that dissolves in one unit volume of liquid at concerend temp where the partial pressure of the gas above the liquid is one atmosphere

Question 6

oswald solubility coefficient

Answer 6

volume of gas that dissolves in one unit volume of liquid at the temp concerned independant of partial pressure
