The lead is absorbed by the skin and over a long time it affects the human nervous system. "Hatters shakes" is an industrial disease due to the felt used in the hat-making industry, having to be treated by hand with lead compounds. Hence "as mad as a hatter" is an old-fashioned synonym. (see also "Alice in Wonderland" - cira the mad hatters tea party).
Lead(II) Sulfide = PbS Lead(IV) Sulfide = PbS2
Lead IV Sulfide is PbS2
Lead Sulfide is PbS.
Lead sulfide is a black solution. It is insoluble in water and is a precipitate. The principle of the lead acetate test is the formation of lead sulfide.
lead(II) sulfide Sulfur has an oxidation number of 2. Cross then superscript S^2 down in front of lead and there ya go.
Lead sulfide is chemically notated as Pb(CH3COO)2.
PbS is not an element, it is a compound.Pb is lead and S is sulfur.The name of this compound is commonly known as Lead Sulfide.
In lead (II) sulfide (PbS), each lead ion is surrounded by six sulfide ions in a octahedral arrangement.
Lead acetate paper turns black in the presence of hydrogen sulfide gas. Hydrogen sulfide reacts with lead acetate to form lead sulfide, which is black in color. This reaction is commonly used as a test for the presence of hydrogen sulfide gas.
Lead (II) sulfide would contain one atom of lead per formula unit. Actually, now that I think about it, so would lead (IV) sulfide.
Pb (Lead) + S (Sulphur) -----> PbS (Lead Sulphide)
It has a bad smell that can be detected by our nose, even in small concentrations.Also, people could try taking a sample of air that contains hydrogen sulfide, and let it pass through a solution of lead nitrate, if the gas contained hydrogen sulfide then the solution will become black due to the lead sulfide that was produced.
