Chapter 7 Solutions Flashcards
Suspension
A mixture where large particles of a material are more or less evenly dispersed throughout a liquid or gas
Colloid
A mixture consisting of tiny particles that are intermediate in size between those in solutions and those in suspensions and that are suspended in a liquid, solid, or gas
Emulsion
Any mixture of 2 or more immiscible liquids in which one liquid is dispersed in the other
Solution
A homogeneous mixture of two or more substances uniformly dispersed throughout a single phase
Solute
A substance that dissolves in the solvent
Solvent
The substance where the solute dissolves
Alloy
A solid or liquid mixture of two or more metals
Heterogeneous Mixture
Mixture made of different substances that remain physically separate
Decanting
Pour from one container into another without disturbing the sediment
Immiscible
Not forming a homogeneous mixture when combined
Tyndall Effect
Light scattering by particles in a colloid or else particles in a very fine suspension
Polar Compound
A molecule that has an uneven distribution of electrons
Hydrogen Bonding
Intermolecular force occurring when a hydrogen atom that is bonded to a highly electronegative atom of 1 molecule is attracted to 2 unshared electrons of another molecule
Nonpolar Compound
A compound whose electrons are equally distributed among its atoms
Solubility
The maximum amount of a solute that will dissolve in a given quantity of solvent at a given temperature and pressure
Concentration
The amount of a particular substance in a given volume of solution
Unsaturated Solution
Contains less than the maximum amount of solute that can dissolve
Saturated Solution
Where no more solute can be dissolved under the same conditions
Molarity
The number of moles of solute per liter of solution
Insoluble
Not able to be dissolved
Soluble
Able to be dissolved
Dilute
Make thinner or weaker by adding water or another solvent to it
