H2SO4: colorless, oily liquid, boiling point 330C. A 96 percent solution is used in the laboratory.

Fire Hazard: This is a very powerful, acidic oxidizer which can Ignite or even explode on contact with many materials, i.e. acetic acid ,acetone+ HNOs, alcohols, + H202, NH4OH, HCL, NaOH, and others.

Sulfuric acid has a wide range of uses and plays a part in the production of nearly all manufactured goods.

Ionization

In aqueous solution, the process in which a molecular compound reacts with water and forms ions.

yttrium

A rare trivalent metallic element, found in gadolinite and other minerals. Symbol: Y, at. wt.: 88.905, at. no.: 39, sp. gr.: 4.47. Cf."rare-earth element."

Yttrium has a silver-metallic luster and is relatively stable in air unless finely divided. Turnings of the metal, however, ignite in air if their temperature exceeds 400oC. Yttrium oxide is one of the most important compounds of yttrium and accounts for the largest use. It is widely used in making YVO4 europium, and Y2O3 europium phosphors to give the red color in color television tubes.

Nonelectrolyte

A substance whose aqueous solutions do not conduct electricity.

Equivalence Point

The point at which chemically equivalent amounts of reactants have reacted.

Heat Capacity

The amount of heat required to raise the temperature of a body (of any mass) one degree Celsius.

Bond Energy

The amount of energy necessary to break one mole of bonds of a given kind (in gas phase).The amount of energy necessary to break one mole of bonds in a substance, dissociating the sustance in the gaseous state into atoms of its elements in the gaseous state.

Cathodic Protection

Protection of a metal (making ir a cathode) against corrosion by attaching it to a sacrifical anode of a more easily oxidized metal.

Miscibility

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

Atomic Mass Unit (amu)

One twelfth of a mass of an atom of the carbon-12 isotope, a unit used for stating atomic and formula weights, also called dalton.
