Copper(II) sulfate is the chemical compound with the formula CuSO4. This salt exists as a series of compounds that differ in their degree of hydration. The anhydrous form is a pale green or gray-white powder, whereas the pentahydrate, the most commonly encountered salt, is bright blue.
In the production of hydrogen fluoride, calcium fluoride is treated with sulfuric acid, precipitating calcium sulfate. In the refining of zinc, solutions of zinc sulfate are treated with lime to co-precipitate heavy metals such as barium. Calcium sulfate can also be recovered and re-used from scrap drywall at construction sites.
Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO 4 and related hydrates.In the form of γ-anhydrite (the anhydrous form), it is used as a desiccant.One particular hydrate is better known as plaster of Paris, and another occurs naturally as the mineral gypsum.It has many uses in industry. All forms are white solids that are poorly soluble in water.

Apr 05, 2013· Calcium in cation form is Ca2+ (alkaline earth metal). The sulfate polyatomic ion is SO42- (memorize) Since both ions have the same charge number (2), it means they form an ionic crystal in the 1:1 ratio, meaning CaSO4.
Sep 19, 2009· Calcium sulfate has chemical formula CaSO4. The formula mass is 40.1+32.1+4(16.0) = 136.2 Mass of 2mol of CaSO4 = 2 x 136.2 = 272.4g There are 272.4 grams of calcium sulfate .
The chemical suffix or end part of a chemical name needs careful attention.. There is a big difference between the "ide", "ate" and "ite" suffixes.. 1. As a general rule an "ide" suffix indicates an element. eg. sulfide S 2-, nitride N 3- and phosphide P 3-. The exceptions are hydroxide OH-and cyanide CN-. 2. "ates" and "ites" always contain oxygen. eg. nitrate NO 3-and nitrite NO 2-
When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight.

Anhydrous calcium sulfate and calcium hemihydrate are fine white odorless powders or crystalline solids, while the dihydrate may occur either as a powder or as white lumps. Both hydrates are converted to the anhydrous form upon heating as, for example: CaSO 4 ·2H 2 O → CaSO 4 + 2H 2 O. Anhydrous calcium sulfate is essentially insoluble in water.
Nov 22, 2014· A video explanation of how to write the chemical formula for Calcium Sulfate. Calcium Sulfate is an ionic compound and therefore we need to take into account ionic charges for each element.
Jan 20, 2020· Calcium sulfate is a salt that occurs abundantly in the natural environment and also appears as a byproduct of some industrial processes. It is a compound of calcium, sulfur and oxygen, and in its purest form has the chemical formula CaSO 4; this is known as anhydrous — water-free — calcium sulfate, or the mineral anhydrite.
Calcium Sulfate Hemihydrate is a moderately water and acid soluble Calcium source for uses compatible with sulfates.Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogen atoms with a metal. Most metal sulfate compounds are readily soluble in water for uses such as water treatment, unlike fluorides and oxides which tend to be insoluble.
