  2. Precipitation (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Precipitation_(chemistry)

    [1] [2] The solid formed is called the precipitate. [3] In case of an inorganic chemical reaction leading to precipitation, the chemical reagent causing the solid to form is called the precipitant. [4] The clear liquid remaining above the precipitated or the centrifuged solid phase is also called the supernate or supernatant.

  3. Other examples of this class of compound have been made; many inorganic chemists are now using Fc 2 P 2 S 4 (Fc = ferrocene) as a starting material in reactions investigating the general chemistry of the 1,3,2,4-dithiadiphosphetane 2,4-disulfides, one reaction for this is that the Fc 2 P 2 S 4 compound and all its derivatives are red which make ...

    en.wikipedia.org/wiki/Silver_phosphate

    Silver pyrophosphate Ag 4 P 2 O 7 (CAS No. 13465-97-9) [13] can be prepared as a white precipitate from reaction of silver(I) and pyrophosphate ions. Like silver orthophosphate it is light sensitive. Silver orthophosphate turns red on exposure to light. [14] It has a density of 5.306 g/cm 3 and a melting point of 585 °C. [15]

  6. Lead(II) azide - Wikipedia

    en.wikipedia.org/wiki/Lead(II)_azide

    RD-1333 lead azide (MIL-DTL-46225), a version of lead azide with sodium carboxymethyl cellulose as a precipitating agent, was developed to meet that need. The Vietnam War saw an accelerated need for lead azide and it was during this time that Special Purpose Lead Azide (MIL-L-14758) was developed; the US government also began stockpiling lead ...

    en.wikipedia.org/wiki/Struvite

    Struvite (magnesium ammonium phosphate) is a phosphate mineral with formula: NH 4 MgPO 4 ·6H 2 O. Struvite crystallizes in the orthorhombic system as white to yellowish or brownish-white pyramidal crystals or in platy mica-like forms. It is a soft mineral with Mohs hardness of 1.5 to 2 and has a low specific gravity of 1.7. It is sparingly ...

  9. Copper(II) thiocyanate - Wikipedia

    en.wikipedia.org/wiki/Copper(II)_thiocyanate

    Copper(II) thiocyanate can be prepared from the reaction of concentrated solutions of copper(II) and a soluble thiocyanate salt in water, precipitating as a black powder. [2] [3] With rapid drying, pure Cu(SCN) 2 can be isolated. Reaction at lower concentrations and for longer periods of time generates instead copper(I) thiocyanate. [4]
