Cobalt is a chemical element with the symbol Co and atomic number 27. Like nickel, cobalt is ... Cobalt oxides are antiferromagnetic at low temperature: CoO
Cobalt oxide is a multifunctional, antiferromagnetic p-type semiconductor (with a direct optical bandgap of 1.48 and 2.19 eV) (Raman et al., 2016) has been used in electrochromic sensors, energy storage, heterogeneous catalysis, pigments, dyes, and in lithium ion rechargeable batteries as an anode material (Askarinejad
Sulphur is determined by Iodate titration or IR detection. A total of 97% of sulfur in the sample is converted to sulphur dioxide by burning the sample in oxygen at high temperatures. The absorbing solution used in this method is potassium iodide and it contains a starch indicator.
Sulfur (in nontechnical British English: sulphur) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature.
