Solutions and Solubility

Question 1

Solubility curves of gases

Answer 1

decrease with temperature
increase in pressure also increases solubility in gases

Question 2

Super saturated solution

Answer 2

a solution that contains more then the maximum quantity of solute that it should at a given temperature and pressure

Question 3

Unsaturated solution

Answer 3

a solution in which more solute can dissolve at a given temperature and pressure

Question 4

Saturated solution

Answer 4

a solution that contains the maximum quanitity of solute at a given temperature or pressure

Question 5

Solubility

Answer 5

the quanitity of solute that can dissolve in a given quantity of solvent. (often represented as the maximum mass of solute that can be dissolved per 100 g of water at a given temp)

Question 6

miscible

Answer 6

able to mix to form a solution, usually describing the liquids that mix with eachother in all proportions to form a solution (ie. acetone and water)

Question 7

immisicible

Answer 7

unable to mix to form a solution, usually describing two solutions that do not readily mix. (water and oil).

Question 8

Concentration

Answer 8

tell us the ratio of solute to solvent in a solution. Units are the quantity of volume to solute to volume (mol/L, g/L, etc)
