Lead and copper electrodes are immersed in sulfuric acid flowing at a rate of 510L/min. Red lead has been used as a pigment for primer paints for iron objects. This white crystalline powder is more soluble than the diiodide, but less than the dibromide and the dichloride. [9] The tetrachloride is obtained upon dissolving the dioxide in hydrochloric acid; to prevent the exothermic decomposition, it is kept under concentrated sulfuric acid. It is soluble in nitric and acetic acids, from which solutions it is possible to precipitate halide, sulfate, chromate, carbonate (PbCO3), and basic carbonate (Pb3(OH)2(CO3)2) salts of lead. The reaction is as follows: Plumbic oxide when swallowed and inhaled is toxic. Lead oxide (PbO 2, with lead as the Pb 4+ ion) is among the stronger oxidizing agents in acidic solution, but it is comparatively weak in alkaline solution.
