Hydrochloric acid with iron (II) sulphide « on: September 13, 2008, 11:18:55 PM » In an experiment to prepare H2S, 100mL of 0.500mol/L HCL solution was added to 1.10g of solid FeS.Which reagent is in excess? Please show me how to work this out! Logged nj...
Microscopical and chemical examination of intertidal flats of the Wash indicate that phases of iron corresponding to ferric hydroxide and iron monosulphide are involved in the early diagenetic formation of pyrite, the first being an important source of the iron. Sedimentological data are tested against...

iron sulphides (Farquhar et al., 2002) or mixed-valence iron minerals (Jönsson and Sherman, 2008)) support the re-adsorption of dissolved As species. However, the microbially-mediated reduction of Fe(III)-(oxyhydr)oxides also leads to dissolved ferrous Fe (Fe(II)) in solution. In the ...
Iron is selectively extracted from an iron compound containing substance by a process comprising converting the iron compound in a portion of the substance to metallic iron, treating the remaining compound with aqueous hydrochloric acid to form a solution or suspension, adding the converted portion to...
Iron sulphide contaminates in silica sand are decreased by leaching with a solution of sodium, potassium or calcium hypochlorite, at an acid pH, e.g from 1-3. The hypochlorite may be obtained by the reaction of Cl2 on a solution of Ca(O... CHUBB PHILIP A. - US 被引量: 4发表: 196...
