The properties of ruthenium and osmium compounds are often similar. The +2, +3, and +4 states are the most common. The +2, +3, and +4 states are the most common. The most prevalent precursor is ruthenium trichloride , a red solid that is poorly defined chemically but versatile synthetically.
With its similar properties to and lower cost than rhodium, electric contacts are a major use of ruthenium. The ruthenium plate is applied to the electrical contact and electrode base metal by electroplating or sputtering. Osmium is a hard but brittle metal that remains lustrous even at high temperatures. It has a very low compressibility.

Ruthenium tetroxide is reduced by cold dilute potassium hydroxide to form black potassium perruthenate, KRuO 4, with ruthenium in the +7 oxidation state. Potassium perruthenate can also be produced by oxidising potassium ruthenate, K 2 RuO 4, with chlorine gas. The perruthenate ion is unstable and is reduced by water to form the orange ruthenate.

A non-physical standard state is one whose properties are obtained by extrapolation from a physical state (for example, a solid superheated above the normal melting point, or an ideal gas at a condition where the real gas is non-ideal). Metastable liquids and solids are important because some substances can persist and be used in that state ...
