Zincatum (e verbo zincum + suffixo -atum) est zincifera substantia chemica. Vero est quidlibet ex his:

  • Sal cum ionte Zn(OH)42−, quod ion tetrahydroxozincatum appellatum est, ut CaZn(OH)4.2H2O [1] vel Na2Zn(OH)4[2] vel anion polymericum [Zn(OH)3] in, e.g., NaZn(OH)3· H2O [3]

Pro patina[recensere | fontem recensere]

Zincatum industriae ad patinam pertinenti solutionem alkalicam significet quae patinam zinci ad aluminium addit ante patinam niccoli. Patina zinci hac solutione sine electricitate additur, i.e. non electrolyse. Atomus aluminii zincum ex zincato in hoc modo summovet:[5]

3 Zn(OH)42− + 2 Al → 3 Zn + 2 Al(OH)4 + 4 OH

Electrolyse patina zinci ad chalybem hac solutione addatur.[6]

Nomenclatura[recensere | fontem recensere]

In nomenclatura -zincatum est suffixum quod aniontem polyatomicam significat qui zinci atomum centralem capit. Per exemplis, tetrachlorozincatum, ZnCl42−, tetrahydroxozincatum, Zn(OH)42− et tetranitratozincatum, Zn(NO3)42−. Recentior, legibus IUPAC nomenclaturae ad inorganicam chemicam anno 2005 appelleretur ZnCl42− ut tetrachloridozincatum(2−) et Zn(OH)42− ut tetrahydroxidozincatum(2−).

Chemica aquosa zincati[recensere | fontem recensere]

Nunc accipitur quod copia iontum in solutione alkalica ZnO vel Zn(OH)2 iontes Zn(OH)42− continet.[7] Creditus est autem quod analyse spectroscopica Ramaniana iontes ZnO22− lineales indicantur.[8]
