Potassium selenate is produced by the reaction of selenium trioxide and potassium hydroxide.. SeO 3 + 2 KOH → K 2 SeO 4 + H 2 O. Alternatively, it can be made by treating selenous acid with potassium hydroxide, followed by oxidation of the resulting potassium selenite with bromine water.
Terraria: A bright-green metal found deep beneath the jungle, implied to be the toughest ore that can be mined from the ground (topped only by Luminite, a material dropped by the final boss). True to its name, Chlorophyte has plant-themed properties, and can be used to craft armor and weapons that harness the powers of plants.

[89] By May 2022, over 44.5 million copies of Terraria had been sold, making it one of the best-selling video games of all time. The total is ...
Selenite, satin spar, desert rose, and gypsum flower are crystal habit varieties of the mineral gypsum.. All varieties of gypsum, including selenite and alabaster, are composed of calcium sulfate dihydrate (meaning that it has two molecules of water), with the chemical formula CaSO 4 ·2H 2 O. Selenite contains no selenium, the similar names both derive from Greek selḗnē (σελήνη 'Moon').
Iron(III) selenite is an inorganic compound with the chemical formula Fe 2 (SeO 3) 3. It exists anhydrous form and as various hydrates. It exists anhydrous form and as various hydrates. The heptahydrate is produced by the reaction of ferric chloride and selenous acid (or sodium selenite ) at a pH of 1.05. [ 3 ]
A selenate selenite is a chemical compound or salt that contains selenite and selenate anions (SeO 3 2-and SeO 4 2-). These are mixed anion compounds . Some have third anions.
Sodium hydrogen selenite. Sodium hydrogen selenite is an inorganic chemical consisting of a ratio of one hydrogen, one sodium, three oxygen, and one selenium atom. It is the sodium salt of the conjugate base of selenous acid. This compound finds therapeutic application for providing the essential trace element selenium.
The element selenium exhibits several valence states. Selenate is the least reduced, followed by selenite, and elemental selenium; selenide is even more reduced than elemental selenium. [6] The valence state is an important factor to the toxicity of selenium. Selenate is the form required by organisms that need selenium as a micronutrient.
