Precipitation (chemistry)

When potassium iodide solution reacts with lead(II) nitrate solution, a yellow precipitate of lead(II) iodide is formed. The precipitation may occur if concentration of a compound exceeds its solubility (such as when mixing solvents or changing their temperature). Precipitation may also occur rapidly from a supersaturated solution.

Lead Essential Chemical Industry

Lead for recycling may be in the form of scrap metal (roofing sheet, for example), or compounds of lead, such as the pastes from lead acid batteries. Clean metallic lead can be melted and refined directly, but compounds and lead alloys require smelting, using processes similar to those used with lead ores.

It's Elemental The Element Lead

Lead has been known since ancient times. It is sometimes found free in nature, but is usually obtained from the ores galena (PbS), anglesite (PbSO 4), cerussite (PbCO 3) and minum (Pb 3 O 4).Although lead makes up only about 0.0013% of the earth's crust, it is not considered to be a rare element since it is easily mined and refined.
