'''Kopparkarbonat''' är en kemisk förening av [[koppar]] och [[karbonat]]-joner. Den förekommer naturligt som [[mineral]]erna [[malakit]] och [[azurit]].<br />
<br />
==Framställning==<br />
Kopparkarbonat bildas på kopparytor som är oskyddade mot väder och vind. [[Syre]], [[koldioxid]] och [[vattenånga]] i luften samverkar till att angripa kopparn och bilda ett grönt lager av [[kopparhydroxid]] och kopparkarbonat.<br />
:<math>\rm 2\ Cu + H_2O + CO_2 + O_2 \rightarrow Cu(OH)_2 + CuCO_3</math><br />
<br />
==Egenskaper==<br />
När det upphettas till ca 200&nbsp;°C så sönderfaller kopparkarbonat till [[svart kopparoxid]] och [[koldioxid]]<br />
:<math>\rm CuCO_3\ \xrightarrow{heat}\ CuO + CO_2</math><br />
<br />
Kopparkarbonat är inte [[hygroskopisk]]t i egentlig mening eftersom det inte binder [[kristallvatten]], men det kan bilda [[hydroxid]]föreningarna Cu<sub>2</sub>(CO<sub>3</sub>)(OH)<sub>2</sub> och Cu<sub>3</sub>(CO<sub>3</sub>)<sub>2</sub>(OH)<sub>2</sub>. Mängden hydroxider kan få färgen att skifta från blekt grön till djupblå.<br />
