Additive is a substance added to a material to improve its properties in some way.

It is soft, lightweight, silvery-white metal. Anodising is a method of coating objects made of aluminium with a protective oxide film, by making them the anode in an electrolytic bath containing an oxidising electrolyte. Acylaction reaction involves the introduction of an acyl group RCO- into a compound. An alkyl halide is reacted with an alcohol or a carboxylic acid anhydride e. An alkyl halide is reacted with an alcohol or a carboxylic acid anhydride e.

Pieces of zinc or magnesium alloy are attached to pump bodies and pipes. The introduction of an acetyl group CH 3 CO- katodnaa acetylation, a process used for protecting -OH groups in organic synthesis.

A thin sheet of metal can afford protection to the skin. The origin of the name comes from the Latin word alumen meaning alum.

Groundbed is a buried item, such as junk steel or graphite rods, that serves as the anode for the cathodic protection of pipelines or other buried structures.

The anode corrodes, thereby providing the desired sacrificial protection. There are two major variations of the cathodic method of corrosion protection. The iron pipe will be connected to a more reactive metal such as magnesium through cooper wires, the magnesium will donate its electrons to the iron preventing it from rusting.

By protection of the environment, the following is ensured: The protected metal becomes the cathode and does not corrode.

CHEMISTRY GLOSSARY

Metal reacts violently with oxidants. Metal reacts violently with oxidants. The anode corrodes, thereby providing the desired azstita protection. Anodising can also be used to produce a decorative finish by formation of an oxide layer that can absorb a coloured dye.

A thin sheet of metal can afford protection to the aktodna. The sacrificial anodes must be replaced periodically as they corrode. Cathodic protection is a process in which a structural metal, such as iron, is protected from corrosion by connecting it to a metal that has a more negative reduction half-cell potential, which now corrodes instead of iron.

Iron which is oxidises will immediately be reduced back to iron. By protection of the environment, the following is ensured: Exposed surfaces quickly form protective oxide coating. There are two major variations of the cathodic method of corrosion protection. The iron pipe will be connected to a more reactive metal such as magnesium through cooper wires, the magnesium will donate its electrons to the iron preventing it from rusting. Aluminium is obtained by electrolysis from bauxite.

The introduction of an acetyl group CH 3 CO- is acetylation, a process used for protecting -OH groups in organic synthesis. The protected metal becomes the cathode and does not corrode.
