Lesson 3 - Gases in the sea Flashcards
1
Q
Henry’s Law states that:
A
C = KH (a constant) x p. Concentration of a solvent at a know temperature is proportional to the partial pressure of the dissolving gas.
2
Q
When does a liquid become ‘saturated’
A
When it is at equilibrium with the gas above it
3
Q
Name 3 control factors of saturation (3)
A
Partial pressure of gas, temperature, composition of liquid
4
Q
What is partial pressure
A
The pressure exerted by a single gas if it occupied the same volume alone.
5
Q
Trend between salinity and oxygen saturation
A
Salinity decreases how much oxygen can be dissolved at saturation
6
Q
Oxygen saturation in a sample equation
A
Oxygen saturation in a sample = G/G’ x 100
Observed concentration/ solubility of the gas in water of the same temp and saline x100
