Types of Solutions
|
Aqueous,
|
|
|
Solute
|
The thing that is being dissolved
|
|
|
Solvent
|
The thing that does the dissolving
|
|
|
Saturated
|
When a solution contains as much solute as will dissolve at that temperature
|
|
|
Unsaturated
|
A solution that is not saturated.
|
|
|
Concentrated
|
A relatively large amount of solute is dissolved in a concentrated solution (strong coffee).
|
|
|
Dilute
|
Not concentrated (weak coffee).
|
|
|
supersaturated
|
When a solution’s concentration surpasses its saturation point
|
|
|
Mass percent
|
"Mass of solute
|
|
|
Reasons for Molarity over Mass Percent
|
Sometimes, volume is preferable to mass
|
|
|
|
"Moles of solute
|
|
|
Standard Solution
|
A solution whose concentration is accurately known.
|
|
|
(5) steps for solving stoichiometric Problems involving solutions
|
"(1): Write balanced equation
|
|
|
Neutralization reaction
|
Acid based reaction
|
|
|
Equivalent of an acid
|
amount of that acid that can furnished 1 mol of H+ ions
|
|
|
Equivalent of a base
|
the amount of that base that can furnish 1 mol of OH ions
|
|
|
Equivalent weight
|
the mass in grams of 1 equivalent of that acid or base
|
|
|
Solution
|
A homogeneous mixture. The solubility of a solute in a given solvent depends on the interactions between the solvent and solute particles. Water dissolves many iconic compounds and compounds with polar molecules. Non-polar solvents tend to describe non-polar solutes. “like dissolves like.”
|
|
|
Dilution
|
Solvent is added meaning moles of solute before dilution are equivalent the moles of solute after dilution
|
|
|
Normality
|
Number of equivalents per liter of solution. One equivalent of acid is the amount of acid that furnishes 1 mol of H+ ions. ONe equivalent of base is the amount of base that furnishes 1 mol of OH- ions.
|
|
|
Boiling point elevation
|
|
|
|
Freezing point depression
|
|
|
|
Vapor pressure
|
|
|
|
3 colligative properties.
|
Freezing point of depression, Boiling point of elevation, vapor pressure
