End Point

The point at which an indicator changes colour and a titration is stopped.

Acetic Acid

CA3COOH, clear, colorless liquid, pungent odor. Boiling point 140C, flash point 54C (closed cup), autoignition temperature 38OC.

Law of Combining Volumes (Gay-Lussac's Law)

At constant temperature and pressure, the volumes of reacting gases (and any gaseous products) can be expressed as ratios of small whole numbers.

 

Absolute Zero

The zero point on the absolute temperature scale, -273.15°C or 0 K, theoretically, the temperature at which molecular motion ceases. The concept of an absolute zero temperature was first deduced from experiments with gases. When a fixed volume of gas is cooled, its pressure decreases with its temperature. Absolute zero physically possesses quantum mechanical zero-point energy.

Flammable

A liquid as defined by NFPD and DOT as having a flash point below 37.8°C (100°F).

Debye

The unit used to express dipole moments.

Periodic Law

The properties of the elements are periodic functions of their atomic numbers.

Coordination Compound or Complex

A compound containing coordinate covalent bonds.

Hydrocarbons

Compounds that contain only carbon and hydrogen.

Faraday's Law of Electrolysis

One equivalent weight of a substance is produced at each electrode during the passage of 96,487 coulombs of charge through an electrolytic cell.
