If you’ve ever had hot chocolate or other flavored dry drink mixes that don’t evenly dissolve or soap scum on your bathtub, you’ve run into solubility issues. Solubility refers to a compound’s ability to dissolve in water, and can vary depending on temperature and pressure. Some compounds will form an aqueous solution while others form precipitates or solids, and some react with water to produce other substances.

Lead fluoride, also known as PbF2, is a sparingly soluble chemical that occurs naturally in the environment. It is used in low melting glass coatings to reflect infrared radiation and in phosphors for television tube screens. It is also used to reduce the corrosion of automobile battery terminals.

It is toxic at high levels, causing the nervous system to become disrupted, leading to seizures and coma. It is also an embryocide, destroying sperm and reducing fertility in humans and animals.

It is listed as a hazardous substance under Section 311(b)(2)(A) of the Federal Water Pollution Control Act and further regulated by the Clean Water Act Amendments of 1977 and 1978. Contact with the skin can cause burns, and inhalation can irritate the nose and throat. It can also cause protoplasmic poisoning, which affects the brain and causes symptoms such as headache, irritability, mood changes, reduced memory, and disturbed sleep. It can also cause gastrointestinal disturbances. Lead fluoride has been shown to cause cancer in animals. The IARC classifies it as a possible carcinogen.
