Solutions – Chemistry Flashcard

Three things that determine how fast a substance dissolves
Agitation, temperature, and the surface area of the dissolving particles.
Determines whether a substance will dissolve
The compositions of the solvent and solute.
Solvent
The dissolving medium in a solution.
Solution
A homogeneous mixture consisting of solutes dissolved in a solvent.
Solute
Dissolved particles in a solution.
Saturated Solution
A solution containing the maximum amount of solute for a given quantity of solvent at a constant temperature and pressure.
Solubility
The amount of solute that dissolves in a given quantity of a solvent at a specified temperature and pressure to produce a saturated solution. Often expressed in grams of solute per 100 g of solvent.
Unsaturated Solution
Contains less solute than a saturated solution would at a specified temperature and pressure.
Miscible
The ability of one liquid to dissolve in all proportions with another liquid.
Partially Miscible
Part of the liquid will dissolve in another liquid.
Immiscible
Liquids that are insoluble in each other.
Supersaturated Solution
Contains more solute than it can theoretically hold at a given temperature.
Does greater temperature increase or decrease the solubility of most substances?
Higher temperature increases the solubility of most substances.
Does greater temperature increase or decrease the solubility of most gases?
Higher temperature decreases the solubility of most gases.
Henry’s Law
At a given temperature, the solubility (S) of a gas in a liquid is directly proportional to the pressure (P) of the gas above the liquids. S1/P1 = S2/P2.
