Chapter 7
Alloy Ð A solid or liquid mixture of two or more metals.
Colloid Ð A mixture consisting of tiny particles that are intermediate in size between those in solutions and those in suspensions and are suspended in a solid, liquid or gas.
Concentration Ð the amount of
a particular substance in a given quantity of a mixture solution or ore
Emulsion Ð any mixture of two or more immiscible liquids in which one liquid is dispersed in the other.
Hydrogen bonding Ð the intermolecular force occurring when a hydrogen atom that is bonded to a highly electronegative atom of one molecule s attracted to two unshared electrons of another molecule
Molarity Ð an expression of the concentration of a solution in moles of dissolved solute per liter of solution
Nonpolar Compound Ð a compound whose electrons are equally distributed among its atoms
Polar compound Ð A molecule that has an uneven distribution of electrons. It has a regional charge.
Saturated Solution Ð A solution that cannot dissolve any ore solute under the given conditions.
Solubility Ð the maximum amount of a solute that will dissolve in a given quantity of solvent at a given temperature and pressure.
Solution Ð a Homogeneous
mixture of two or more substances uniformly dispersed throughout a single
phase.
Solvent Ð In a solution, the
substance in which the solute dissolves.
Supersaturated solution Ð A
solution that holds more dissolved solute than is required to reach equilibrium
at a given temperature.
Suspension Ð A mixture in which particles of a material are more or less evenly dispersed through a liquid or gas and can settle out.
Unsaturated solution ÐA solution that contains less solute that a saturated solution does and that is able to dissolve additional solute
