Brass reaction with sulfur
WebOxidation number of nitrogen is protected in this reaction. Sulfur and hot concentrated nitric acid reaction. Sulfur is oxidized into sulfuric acid (H 2 SO 4) and nitric acid will be reduced to nitrogen dioxide (NO 2). This reaction is an example to oxidizing ability of nitric acid. WebOxidation of sulfide is a complicated process. Depending on the conditions, the oxidation can produce elemental sulfur, polysulfides, polythionates, sulfite, or sulfate. Metal sulfides react with halogens, forming sulfur and metal salts. 8 MgS + 8 I 2 → S 8 + 8 MgI 2 Metal derivatives [ edit]
