Litharge lead is a red or yellow crystals of various shades, poorly soluble in water and ethanol. It is a binary inorganic compound of lead metal and oxygen. Thermodynamically stable at room and lower temperatures, characterized by high anticorrosive properties. Highly toxic. It is diamagnetic, h..
Lead is an element of the 14th group (according to the outdated classification - the main subgroup of the IV group), the sixth period of the periodic system of chemical elements of D.I. Mendeleev, with atomic number 82 and, thus, contains the magic number of protons. Lead, a simple substance (CAS n..
Lead sulphate PbSO4, also called "lead sulphate", precipitates as a white powdery precipitate when dilute sulfuric acid is added to lead salt solutions. It is hardly soluble in water (about 40 mg / l). It dissolves much better in concentrated strong acids (hydrochloric, nitric, sulfuric). When di..
Lead chloride PbC12 forms white rhombic crystals with a silky sheen. Specific gravity 5.9, melting point 498 В° C, boiling point 954 В° C. Lead chloride is moderately difficult to dissolve in water. Therefore, it is precipitated from not too dilute solutions of lead (II) salts when ions are added ..
