  • The most expensive metal in the world

    Do you think the most expensive metal is gold? No! On earth there are more valuable metals. But we need to divide the value of metals that occur in nature, and metals - isotopes, which are obtained in special laboratories. Let’s look at natural metals first.



Most Popular

Octahedral

A term used to describe molecules and polyatomic ions that have one atom in the center and six atoms at the corners of a octahedron.

Molarity

Number of moles of solute per litre of solution.

Double Salt

Solid consisting of two co-crystallized salts.

 

Fractional Precipitation

Removal of some ions from solution by precipitation while leaving other ions with similar properties in solution.

Sulfuric Acid

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.

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.

Hydrolysis Constant

An equilibrium constant for a hydrolysis reaction.

Coordination Sphere

The metal ion and its coordinating ligands but not any uncoordinated counter-ions.

Carbanion

An organic ion carrying a negative charge on a carbon atom.

Saccharide

An organic compound containing a sugar or sugars.
