Solute - a substance that is dissolved in a solvent
Soluble - having high solubility
Solvent - medium in which a solute is dissolved; usually the liquid component of the solution
Solution - a homogeneous mixture of dissolved; usually the liquid component of the solution
Solubility - concentration of a saturated solution of a solute in a solvent
Saturated solution - a solution that is in equilibrium with undissolved solute and \contains the macimum amount of dissolved solute at specified conditions.
Filtration - the process of separating a low-solubility solid from a liquid using a filter
Filtrate - the solution that flows through a filter paper
Concentration - the ration of the quantity of solute to the quantity of solution or solvent
Concentrated solution - a nomogeneous mixture with a relatively high ratio of solute to solution; e.g. a saturated solution
Dilute solution - a homogeneous mixing of one substance with other
Dilution - the process of one substance with another
unssturated solution -
supersaturated solution - more than maximum
Molar concentration - [C] the amount of solute (in moles) in one little of solution
Molar solubility - [C] the molar concentration of a sturated solution
Electrolytes - a solute that forms a solution that conducts an electric curvent; a substance that ionized in water to form individual ions
Nonelectrolytes - a solute that dorms a solution that does not conduct an electric curvent; a substanve that does not produce ion in solution.
Dissoliation - the separation of an ionic compound into individual ions in a soluvent
Spectatorions -
Dilution
When a solution is diluted, made soluvent is added but the amount of solute is unchanged.
How would you diltes 20 ml of 2M HCl to .5M?
Since V2 = 80mL you must substanct V1 from it: 80mL-20mL =60mL.
You must add 60mL of H2O to 20 mL of 2M to make a 0.5 solution.
