Hydroxide - as it is in many encyclopedias and chemistry books

Hydroxides are chemical compounds that contain a hydroxide ion. As only moderate with chemical confidant it is now really just smart as before: The technical term "hydroxides" was replaced by the (equally unintelligible) technical term "hydroxide". However, you can not get around this specific and very important ion.

The hydroxide - a simple explanation

  • Ions are initially charged molecules or atoms. They are formed when an atom or molecule an extra electron "missed" or "snatches".
  • Some compounds, such as the well-known sodium chloride NaCl, caused by two ion, namely, the positively charged Na ion and the negatively charged ion Cl enter, by electric attraction forces a connection. Solving those substances with ionic bonds, for example in water, then formed in the solution, the ions and provide the electrical conductivity.
  • Even water gets (very small scale) ions, namely as H + - ion and OH -, also known as the hydroxide, since it consists of hydrogen (hydrogen) and oxygen (Oxygen).
  • A solution contains excess hydrogen ions, so it is acidic, it contains excess hydroxide ions, it reacts as a base.

So what are Hydroxide?

  • Thus hydroxides are chemical compounds containing such a hydroxide ion, so a OH group,.
  • However, these groups fulfill a specific function: Solving hydroxides, for example in water, then cleaves the compound the OH ion from dissociated it.
  • The simplest hydroxides consist of an alkali metal such as sodium, potassium or cesium and an OH group. The compounds are powdery or salt form. But also more complicated metal complexes have the OH groups as ligands are referred to (in the broad sense) as hydroxides.
  • The most common is sodium hydroxide NaOH, which can be bought as a white powder and is used for soap making. Solv- NaOH in water (caution: heat up and injected; goggles) so split off the OH ion and forms the known caustic soda, the litmus paper (and many other dyes) umfärbt.
  • In general, the aqueous solutions of hydroxides are soapy oily, too slippery, and burning in the eyes (!).
