Chemical compound

Silver carbonate is the chemical compound with the formula Ag_twoCO_three. This salt is yellow simply typical samples are grayish due to the presence of elemental silver. It is poorly soluble in water, similar most transition element carbonates.

Preparation and reactions [edit]

Silver carbonate tin can be prepared by combining aqueous solutions of sodium carbonate with a deficiency of silver nitrate.^[viii]

${\displaystyle {\ce {2 AgNO3(aq) + Na2CO3(aq) -> Ag2CO3(s) + 2 NaNO3(aq)}}}$

Freshly prepared silverish carbonate is colourless, merely the solid quickly turns yellow.^[9]

Silver carbonate reacts with ammonia to give the diamminesilver(I) ([Ag(NH₃)₂]⁺) complex ion. Like other diamminesilver(I) solutions, including Tollen's reagent, in that location is a possibility that explosive Argent nitride may precipitate out of the solution. Argent nitride was previously known as fulminating silver but due to confusions with silverish fulminate it has been discontinued past the IUPAC.^[10]

With hydrofluoric acid, it gives silver fluoride.

The thermal conversion of silver carbonate to silver metallic proceeds via germination of silver oxide:^[xi]

${\displaystyle {\ce {Ag2CO3 -> Ag2O + CO2}}}$

${\displaystyle {\ce {ii Ag2O ->iv Ag + O2}}}$

Uses [edit]

The primary utilize of silver carbonate is for the production of silver powder for use in microelectronics. It is reduced with formaldehyde, producing silver costless of alkali metals:^[ix]

${\displaystyle {\ce {Ag2CO3 + CH2O -> 2 Ag + 2 CO2 + H2O}}}$

Silver carbonate is used as a reagent in organic synthesis such as the Koenigs-Knorr reaction. In the Fétizon oxidation, silver carbonate on celite serves every bit an oxidising agent to class lactones from diols. It is also employed to convert alkyl bromides into alcohols.^[viii] As a base, information technology has been used in the Wittig reaction.^[12] and in C-H bail activation.^[13]
