Which traditional Indian (Ayurvedic) medicines contain
Lead is present in very few Ayurvedic medicines. Mainly the medicine which has "Naga Bhasma" as its component. Also other heavy metals like mercury & sulfide are used traditionally in Ayurveda & Chinese medicines from many centuries. Many scientific studies have found "Mercuric Sulfide" or Cinnabar as a very stable salt.
Binary Ionic Compounds Containing a Metal Ion With a
A binary ionic compound is composed of ions of two different elements - one of which is a metal, and the other a nonmetal. For example, iron(III) iodide, FeI 3, is composed of iron ions, Fe 3+ (elemental iron is a metal), and iodide ions, I-(elemental iodine is a nonmetal). Rule 1.

Lead(II) sulfide Facts for Kids | KidzSearch.com
Lead(II) sulfide is a black solid. It does not react with acids. It reacts with air at a high temperature to make lead(II) oxide. It is one of the least toxic forms of lead. This does not mean that it is not toxic, though. It is the result of a test for hydrogen sulfide. Paper soaked in lead(II) acetate is passed through hydrogen sulfide.
Lead can be extracted from lead(II) sulfide, PbS, in two
Lead can be extracted from lead(II) sulfide, PbS, in two stages. Stage 1: Lead(II) sulfide is heated in air. It reacts with oxygen to produce lead(II) oxide and sulfur dioxide. Stage 2: The Lead(II) oxide is then heated in a blast furnace with coke. (a) Write a chemical equation for the reaction in Stage 1.
