The World Health Organization (WHO) stated a legal limit of 50 ppb for lead in 1995, which is decreased to 10 ppb in 2010. In what way and in what form does lead react with water? Under normal conditions lead does not react with water. However, when lead comes in contact with moist air reactivity with water increases.
When both oxygen and water are present, metallic lead is converted to lead hydroxide (Pb(OH) 2): 2Pb(s)+ O 2 (g) + 2H 2 O(l) -> 2 Pb(OH) 2 (s) Solubility of lead and lead compounds. Elementary lead does not dissolve in water under normal conditions (20 o C, and pressure = 1 bar). It may however occur dissolved in water as PbCO 3 or Pb(CO 3) 2 2-. A well-known example of a water soluble lead compound is lead sugar (lead(II)acetate), which derived its name from its sweet nature. Lead frequently binds to sulphur in sulphide form (S 2-), or to phosphor in phosphate form (PO 4 3-).
