Cadmia/tuttia/tutty – probably zinc carbonate. Calamine – zinc carbonate. Calomel/horn quicksilver/horn mercury – mercury(I) chloride, a very poisonous purgative formed by subliming a mixture of mercuric chloride and metallic mercury, triturated in a mortar and heated in an iron pot. The crust formed on the lid was ground to powder and ...
Compounds with zinc in the oxidation state +1 are extremely rare. [5] The compounds have the formula RZn 2 R and they contain a Zn — Zn bond analogous to the metal-metal bond in mercury(I) ion, Hg 2 2+. In this respect zinc is similar to magnesium where low-valent compounds containing a Mg — Mg bond have been characterised. [6]
Zinc(II) forms a colorless tetraammine with the formula [Zn(NH 3) 4] 2+. [13] Like most zinc complexes, it has a tetrahedral structure. Hexaamminenickel is violet, and the copper(II) complex is deep blue. The latter is characteristic of the presence of copper(II) in qualitative inorganic analysis.
Lead-tin-yellow: PbSnO 4 or Pb(Sn,Si)O 3. Titanium pigments. Titanium yellow (PY53): NiO·Sb 2 O 3 ·20TiO 2; Tin pigments. Mosaic gold: stannic sulfide (SnS 2). Zinc pigments. Zinc yellow (PY36): zinc chromate (ZnCrO 4), a highly toxic substance with anti-corrosive properties which was historically most often used to paint over metals.
More than 1% magnesium in the alloy impairs the flux action, however, as the magnesium oxide layer is more refractory. Another possibility is an inorganic flux composed of zinc chloride or tin(II) chloride, [21] ammonium chloride, and a fluoride (e.g. sodium fluoride).
The flame test carried out on a copper halide. The characteristic bluish-green color of the flame is due to the copper. A flame test is relatively quick test for the presence of some elements in a sample. The technique is archaic and of questionable reliability, but once was a component of qualitative inorganic analysis.
Copper(I) chloride – CuCl; Copper(I) fluoride – CuF; Copper(I) oxide – Cu 2 O; Copper(I) sulfate – CuSO 4; Copper(I) sulfide – Cu 2 S; Copper(II) azide – Cu(N 3) 2; Copper(II) borate – Cu 3 (BO 3) 2; Copper(II) carbonate – CuCO 3; Copper(II) chloride – CuCl 2; Copper(II) hydroxide – Cu(OH) 2; Copper(II) nitrate – Cu(NO 3 ...
