factors affecting solubility

more factors that affect solubility:

==temperature== - the temperature of the solvent influences how much solute will dissolve in it

- found in table g

- solid compounds dissolve more at higher temperature

- gases generally dissolve less at higher temperature

==pressure==

- only affects gasses—more pressure = more gas dissolves\

types of solutions: (we can describe solutions based on how much solute is dissolved in them)

==unsaturated==: solution has less solute than can normally be dissolved at that specific temperature

==saturated==: solution has the maximum solute that can normally be dissolved at that specific temperature

==supersaturated==: solution has more than the maximum solute that can normally be dissolved at that specific temperature

how might this be possible?

==precipitation==: when an insoluble substance comes out of solution as a solid; the actual solid is called a precipitate

how to use table g:

table g shows the number of grams of a substance that can be dissolved in 100 grams of H2O at temperatures between 1°C and 100°C. each curve represents the maximum amount of a substance that can be dissolved at a given temperature. all lines that show an increase in solubility as temperature increases represent solids. the lines for gases slope downward.

==on the curve==, solution is saturated

==under the curve==, solution is unsaturated

==above the curve==, solution is supersaturated
