Chapter 7 Flashcards
Suspension
Suspension is a mixture in which large particles of a material are more/ less evenly dispersed throughout a liquid or gas.
Colloid
Colloid is a mixture consisting of tiny particles that are intermediate in size compared to those of solutions or suspensions and that are suspended in a solid, liquid, or gas.
Emulsion
Emulsion is any mixture of two or more Immiscible liquids in which one liquid is dispersed in the other.
Solution
A solution is a homogenous mixture of two or more substances uniformly dispersed throughout a single phase.
Solute
A solute is the substance that dissolves in the solvent
Solvent
A solvent is the substance in which the solute dissolves
Alloy
Alloy is a solid or liquid mixture of two or more metals.
Heterogeneous mixture
A heterogenous mixture is made of different substances that remain physically separate. They always have more than one phase.
Decanting
Decanting is the process for separation of mixtures by removing a layer of liquid.
Immiscible
Immiscible is liquids that that do not mix with each other.
Tyndall effect
The Tyndall effect is light scattering particles in a colloid or particles in a fine suspension.
Polar compound
A polar compound is a molecule with a geometric arrangement of one side carrying a positive charge and the other side a negative charge.
Hydrogen bonding
Hydrogen bonding is the intermolecular force occurring when a hydrogen atom that is bonded to a highly electronegative atom of one molecule is attracted to two unshared electrons of another molecule.
Nonpolar compound
A nonpolar compound is a compound whose electrons are evenly distributed among its atoms.
Solubility
Solubility is the maximum amount of a solute that will dissolve in a given quantity of a solvent at a given temperature and pressure.
Concentration
Concentration is the amount of a particular substance in a given volume of solution.
Unsaturated solution
An unsaturated solution contains less than the maximum amount of a solute that can dissolve.
Saturated solution
A saturated solution is at a point where no more solute can be dissolved under the same conditions.
Supersaturated solution
A supersaturated solution holds more dissolved solute than is required to reach equilibrium at a given temperature.
Molarity
Molarity is a precise way of measuring concentration.
Insoluble
Insoluble is incapable of being dissolved.
Soluble
Soluble is able to be dissolved. Especially in water.
Dilute
Dilute makes a liquid thinner or weaker by adding water to another solvent to it.
