Chapter 7 Flashcards
Insoluble
Cannot be dissolved
Soluble
Can be dissolved
Solubility
The ability to be dissolved
Suspension
A mixture in which large particles of material are more or less evenly dispersed throughout a liquid or gas.
Heterogeneous mixture
Will not mix but they will separate
Immiscible
Liquids that do not mix with each other.
Decanting
To separate two immiscible liquids by pouring the less dense liquid off the top.
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 two 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
The substance that dissolves in the solvents
Solvent
The substance in which the solute dissolves
Alloy
A solid or liquid mixture of two or more metals
Tyndall effect
When the substances particles are large enough to scatter light that passes through.
Polar compound
A compound that has an uneven distribution of electrons, like water
Hydrogen bonding
The force when a hydrogen atom that is bonded to a highly electronegative atom of one molecule is attracted to two unshared electrons of another molecule.
No polar compound
A compound whose electrons are equally distributed among its atoms.
Concentration
The amount of a particular substance in a given volume of solution
Unsaturated solution
A solution that contains less than the maximum amount of solute that can dissolve
Saturated solution
A solution that is at a point where no more solute can be dissolved under the same conditions.
Supersaturated solution
A solution that holds more dissolved solute than it is required to reach equilibrium at a given temperature.
Molarity
An expression of the concentration of a solution in moles of dissolved solute per liter of solution.
Dilute
To make a liquid thinner or wear,ear by adding another solvent.
