Precipitation may refer to:
  • Precipitation (meteorology)
    Precipitation (meteorology)
    In meteorology, precipitation In meteorology, precipitation In meteorology, precipitation (also known as one of the classes of hydrometeors, which are atmospheric water phenomena is any product of the condensation of atmospheric water vapor that falls under gravity. The main forms of precipitation...

    , rain, sleet, hail, snow and other forms of water falling from the sky
  • Precipitation (chemistry)
    Precipitation (chemistry)
    Precipitation is the formation of a solid in a solution or inside anothersolid during a chemical reaction or by diffusion in a solid. When the reaction occurs in a liquid, the solid formed is called the precipitate, or when compacted by a centrifuge, a pellet. The liquid remaining above the solid...

    , the condensation of a solid from a solution during a chemical reaction
  • Precipitation (horse)

  • Acid precipitation, a type of meteorological precipitation characterized by high acidity
  • Ammonium sulfate precipitation
    Ammonium sulfate precipitation
    Ammonium sulfate precipitation is a method used to purify proteins by altering their solubility. It is a specific case of a more general technique known as salting out....

    , a method of purifying proteins
  • Basic precipitation
    Basic precipitation
    Basic precipitation or Alkaline precipitation occurs when calcium oxide or sodium hydroxide are emitted into the atmosphere, and are absorbed by water droplets in clouds, which then fall as rain, snow, or sleet...

  • Precipitation hardening, a method used to strengthen malleable materials
  • Protein precipitation
    Protein precipitation
    Precipitation is widely used in downstream processing of biological products, such as proteins. This unit operation serves to concentrate and fractionate the target product from various contaminants. For example, in the biotechnology industry protein precipitation is used to eliminate contaminants...
