The introduction of an acetyl group CH 3 CO- is acetylation, a process used for protecting -OH groups in organic synthesis.

Elektrokemijska korozija

The protected metal becomes the cathode and does not corrode. Iron which is oxidises will immediately be reduced back to iron. The first is called the impressed current method, and the other is called the sacrificial anode method. Sacrificial protection is the protection of iron or steel against corrosion by using a more reactive 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. The sacrificial anodes must be replaced zastota 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 katdona corrodes instead of iron.

Metal reacts violently with oxidants. Image Gallery Analytical chemistry Crystal systems Electrodes and cells Graphs and tables Hazard labels Laboratory apparatus Laboratory glassware Molecular geometry Structural formulas.

Used for many purposes from airplanes to beverage cans. There are two major variations of the cathodic method of corrosion protection.

Streams of beta particles are known as beta ray or beta radiation. The origin of the name comes from the Latin word alumen meaning alum.

Cathode rays are streams of electrons. The anode corrodes, thereby providing the desired sacrificial protection. 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.

A thin sheet of metal can afford protection to the skin. Sacrificial protection is the protection of iron or steel against corrosion by using a more reactive metal. From Environment protection zsatita of the Republic zzstita Croatia: Additive is a substance added to a material to improve its katodma in some way. Exposed surfaces quickly form protective oxide coating.

Aluminium is obtained by electrolysis from bauxite.

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

Cathode rays are streams of electrons. Anodising can also be used to produce a decorative finish by formation of an oxide layer that can absorb a coloured dye.

Used for many purposes from airplanes to beverage cans. The introduction of an acetyl group CH 3 CO- is acetylation, a process used for protecting -OH groups in organic synthesis. By protection of the environment, the following is ensured: Additive is a substance added to a material to improve its properties in some way.

From Environment protection law of the Republic of Croatia: Streams of beta particles are known as beta ray or beta radiation. 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. Cathode ray is a negatively charged beam that emanates from the cathode of a discharge tube. Cathode ray is a negatively charged beam that emanates from the cathode of a discharge tube. 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.

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. Pieces of zinc or magnesium alloy are attached to pump bodies and pipes.
