Plumbosolvency is the ability of a solvent, notably water, to dissolve lead.
Plumbosolvency of water can be countered by achieving a pH of 7.5 by increasing the pH with lime or sodium hydroxide (lye), or by providing a protective coating to the inside of lead pipes by the addition of phosphate at the water treatment works.
Achieving this pH has been shown to decrease population blood lead concentrations.
However, lead chloride is fairly soluble in hot water.
