Suez international nitrate company (sinco) the core activity of the company is the production of ammonium nitrate, which is the main raw material used by the factories of sccl in the kingdom of saudi arabia to produce explosives for civil use. Lead(ii) nitrate is an inorganic compound with the chemical formula pb(no3)2. it commonly occurs as a colourless crystal or white powder and, unlike most other lead(ii) salts, is soluble in water. scope of the report: this report focuses on the lead nitr Having extracted the lead as the soluble acetate or nitrate salt, the next question is which reagent to use to detect the presence of lead ions in the extract. home testing kits use one of the following reagents: sodium sulfide – reacts with lead ions to produce lead sulfide, an extremely insoluble salt that is black or dark brown. Three types of clay found in saudi arabia were investigated as potential adsorbents for removing lead from wastewater. tabuk and baha clays were better adsorbents compared to khaiber clay. the pre-existence of lead within the khaiber clay, as revealed by chemical analysis, may have some effect on this finding.
