What is a solution
a homogenous mixture made up from a solvent and a solute
what is a solvent
a substance that has another substance dissolved in it
what is a solute
the substance that is dissolved
what is unsaturated
A solution that does not contain the maximum amount of solute -can still hold more solute at that temperature
what is saturated
The maximum amount of solute that can dissolve at a given temperature
what is supersaturated
holds more solute then theoretically possible at that temperature
in a liquid solvent the solubility of solids ……… when INCREASING temperature and why
-increase -the high temperature increases kinetic energy which means that the ions will move and collide wih each other which also makes their IMF’s weaker
in a liquid solvent the solubility of gases ……… when INCREASING temperature and why
-decrease -when you heat a liquid the gas molecules gain energy and move faster which allows them to escape the liquid more easily so less gas stays dissolved
In a liquid solvent the solubility of gases…. when INCREASING pressure and why
-increases -high pressure forces gas particles into the solvent increasing solubility
what is rate of dissolving
how quickly a solute dissolves in a solvent
what are factors that affect rate of dissolving
-surface area -temperature -aigation
what are the 6 strong acids
HCl (aq) HBr (aq) HI (aq) HNO3 (aq) H2SO4 (aq) HClO4 (aq)
formula for finding PH
-log [H30]
formula for finding [H30]
10 to the power of negative PH
formula for finding PoH
-log [OH]
formula for finding [OH]
10 to the power of negative PoH
