Solubility is a crucial consideration for many laboratory processes. The solubility of a chemical is measured as the ratio of the amount of a solute that dissolves in water to the amount that is present in the solution. For example, lead fluoride has a solubility of 0.07 M in water at 25 degrees Celsius. This means that the concentration of the solute is 0.07 mg of lead per liter of water.
Lead(II) fluoride is a white, odorless solid. It has a molecular formula of PbF2. It is an inorganic compound and is formed through the reaction of lead with hydrogen fluoride. Other products are produced, such as lead(II) chloride and lead(II) iodide.
The solubility of lead(II) fluoride is influenced by the temperature and pressure. If the pressure increases, it will result in an increase in the solubility of the chemical. Also, if the temperature increases, the solubility will decrease.
Lead(II) fluoride has an oral LD50 of 3,000 mg/kg in rats. Exposure to lead fluoride may damage organs, such as the liver. A prolonged exposure to this substance may cause paralysis or death.
Lead fluoride is also used in glass coatings and as a catalyst for the production of picoline. It is also used as a phosphor for television-tube screens and low-melting glasses. Currently, it is available in high purity and submicron powder form. In some applications, such as in optical deposition, lead fluoride is very important.
As a free element, lead occurs naturally. In addition, lead is a useful metal for electrolysis. Besides, it is not irritating to skin and mucous membranes.
