Sulfites or sulphites are compounds that contain the sulfite ion ... which each carry a formal charge of −1, together accounting for the −2 charge on the anion.
The sulfur atom is in the +6 oxidation state while the four oxygen atoms are each in the −2 state. The sulfate ion carries an overall charge of −2 and it is the conjugate base of the bisulfate (or hydrogensulfate) ion, HSO − 4, which is in turn the conjugate base of H 2 SO 4, sulfuric acid.
Sulfide (also sulphide in British English) [2] is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Solutions of sulfide salts are corrosive. Sulfide also refers to large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide.
Consider the sulfate anion (SO 2− 4) with 32 valence electrons; 24 from oxygens, 6 from sulfur, 2 of the anion charge obtained from the implied cation. The bond orders to the terminal oxygens do not affect the oxidation state so long as the oxygens have octets.
Solutions of bisulfite are typically prepared by treatment of sulfur dioxide with aqueous base: [3] SO 2 + OH − → HSO − 3. HSO − 3 is the conjugate base of sulfurous acid, (H 2 SO 3). HSO − 3 is a weak acidic species with a pK a of 6.97. Its conjugate base is sulfite, SO 2− 3: HSO − 3 ⇌ SO 2− 3 + H +
The naturally occurring mineral binary compounds of copper and sulfur are listed below. Investigations of covellite indicate that there are other metastable Cu-S phases still to be fully characterised. [1] CuS 2, villamaninite [2] or (Cu,Ni,Co,Fe)S 2 [3] CuS, covellite, [2] copper monosulfide; Cu 9 S 8 (Cu 1.12 S), yarrowite [4] Cu 39 S 28 (Cu ...
