Chemistry of Metals and Alloys

Minerals are naturally occurring inorganic substances found in the Earth's crust from which metals can be extracted.

Barium sulfate is used as a radiocontrast agent in X-ray imaging of the digestive tract because it is opaque to X-rays and insoluble.

Carbon, aluminium, and sodium are all strong reducing agents used in metallurgy. Iron is generally not used as a reducing agent for these oxides, as it is less reactive than the others.

Metals like zinc are moderately reactive and cannot be extracted from their ores by heat alone; they require a chemical reducing agent like carbon.

German silver is an alloy of copper, nickel, and zinc. Despite its name, it contains zero percent silver.

Brass is a metallic alloy composed primarily of copper and zinc. Bronze, by contrast, is an alloy of copper and tin.

Bronze is an alloy consisting primarily of copper, usually with tin as the main additive. Brass is copper and zinc.

German silver is an alloy of copper, zinc, and nickel. Despite its name, it contains no silver.

stainless steel is formed by mixing C, Ni and Mn.

A galvanic cell, or voltaic cell is an electrochemical cell that derives electrical energy from spontaneous redox reactions taking place within the cell. It generally consists of two different metals connected by a salt bridge ( copper and zinc).

Mixture is impure and a compound is in pure state.

fact

The reactivity of Ag is less than the reactivity of Cu hence get displaced
