is lead ii fluoride soluble in water
The solubility of a compound depends on the forces that interact between the solvent molecules and the solute molecules. The stronger these interactions are, the higher the solubility. The solubility of a compound also increases with the temperature of the solution.
A compound is soluble in a solvent if the bonding energy between it and the solvent is less than its lattice energy. For ionic compounds, the solubility is generally highest in polar solvents. The polarity of the solvent allows its molecules to overcome the solute’s lattice energy by attractive interactions with the ions.
Nonpolar gases are typically the least soluble in water, because they have very weak interaction energies between them and water. However, the solubilities of polar gases such as hydrogen and nitrogen increase with the molecular mass of the gas. This is due to the fact that London dispersion interactions between the solute and solvent become stronger as the size of the molecules becomes larger.
Network solids such as diamond and graphite are insoluble in any solvent with which they do not react chemically because the covalent bonds that hold their atomic structure together are much stronger than any possible intermolecular interactions between the atoms and molecules of the solvent. Most metals are also insoluble in any solvent other than aqueous acids and bases because their delocalized metallic bonding is far stronger than any favorable metal-solvent interactions.
Lead difluoride is prepared by reacting lead hydroxide or carbonate with potassium fluoride, or by the reaction of lead nitrate with hydrofluoric acid. It is used in low melting glasses; in glass coatings to reflect infrared rays; in phosphors for television-tube screens; and in nickel plating of glass. It is a toxic compound. Chronic exposure may cause anemia, a blue line at the gum margin, weakness in the extensor muscles of the wrist joint and other joints, constipation, nausea, vomiting, abdominal pain and vomiting, depression, coma, and death. It can also be absorbed by inhalation or by ingestion and may cause kidney and brain damage.
