Where is cadmium found in nature?
Cadmium is associated with zinc, lead and copper ores - as cadmium sulphide, CdS.
Which material is used in LDR?
Cadmium Sulphide (CdS), Cadmium Selenide (CdSe), Selenium, etc.
When was cadmium discovered?
Cadmium was discovered in 1817.
What happens when hydrogen sulphide passes through cadmium chloride?
when H2S gas i.e. hydrogen sulphide gas is passed through cadmium chloride solution, yellow colored precipitate of cadmium sulphide (CdS) is formed and aqueous hydrochloric acid (HCl) is formed. H2S(g) + CdCl2(aq) -----> CdS(s) + 2HCl(aq)
What solution is absorbs hydrogen sulphide?
Cadmium sulfate solution will absorb H2S, forming CdS.
Who is the Founder of cadmium?
Cadmium was discovered by Friedrich Strohmeyer in 1817 in Germany.
When was cadmium dicovered?
Cadmium was discovered in the year of 1817, I am not sure of the exact date.
What is wurtzite?
A wurtzite is a dark brown mineral, a form of zinc sulphide, often containing iron and cadmium sulphides.
What is a wurtzite?

Why do you use cadmium sulphate in light dependent resistors instead of silicon?
Cadmium sulphide (CdS) has been used since before bulk silicon was available. Besides Silicon is used as a semiconductor for making electronic transistors. Resistors have to be put on it. Cadmium Sulfide is cheap and works fine.
What do you mix to get cadmium yellow?
None. Yellow is a primary color, which means it is not a mixture of any other color, it stands alone. Cadmium is a metal that is mixed into the yellow pigment to give it is brightness. Therefore a cadmium yellow would be a bright yellow as opposed to, say, a yellow ocher.
Date of discovery the cadmium element?
The bivalent transition metal cadmium was discovered in 1817 by the German chemist Friedrich Strohmeyer. The metal melts at a relatively low (321oC) temperature compared to other metals, and it is not found in its pure form in nature. A lot of cadmium is recovered as a byproduct from the refining of zinc (mostly zinc sulfide ores), and, to a lesser degree, lead and copper. A link is provided to the Wikipedia article on cadmium.
