What colour in the intense pigment in cadmium sulphide?
Cadmium television cathode ray tubes. Cadmium sulfide (CdS) is used as a photoconductive surface coating for photocopier drums. Various cadmium salts are used in paint pigments, with CdS as a yellow pigment being the most common. Cadmium selenide is a red pigment, commonly called "cadmium red". To painters who work with the pigment, cadmium provides the most brilliant and durable yellows, oranges, and reds — so much so that during production, these colors are significantly toned down before they are ground with oils and binders or blended into watercolors, gouaches, acrylics, and other paint and pigment formulations. Because these pigments are
Cadmium sulfate hydroxide with dilute sulfuric acid: The anhydrous material is prepared using sodium persulfate: Pure cadmium sulfate occurs as very rare minerals drobecite (CdSO·4HO), voudourisite (monohydrate), and lazaridisite (the 8/3-hydrate). Cadmium sulfate is used widely for the electroplating of cadmium in electronic circuits. It is also a precursor to cadmium-based pigment such as cadmium sulfide. It is also used for electrolyte in a Weston standard cell as well as a pigment in fluorescent screens. Cadmium sulfate Cadmium sulfate is the name of a series of related inorganic compounds with the formula CdSO·HO. The most common form is the monohydrate CdSO·HO, but
