Miscibility

The ability of one liquid to mix with (dissolve in) another liquid.

Capillary Action

The drawing of a liquid up the inside of a small-bore tube when adhesive forces exceed cohesive forces, or the depression of the surface of the liquid when cohesive forces exceed the adhesive forces.

Rate of Reaction

Change in the concentration of a reactant or product per unit time.

Method of Initial Rates

Method of determining the rate-law expression by carrying out a reaction with different initial concentrations and analyzing the resultant changes in initial rates.

Standard Electrodes

Half-cells in which the oxidized and reduced forms of a species are present at unit activity, 1.0M solutions of dissolved ions, 1.0atm partial pressure of gases, and pure solids and liquids.

Saccharide

Electrode Potentials

Potentials, E, of half-reactions as reductions versus the standard hydrogen electrode.

What are Compound Microscopes?

Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses.

The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is the stage, with the illuminator below that.

Valence Electrons

Outermost electrons of atoms, usually those involved in bonding.

Free Radical
