Question

What is the formula for calcium sulfate dihydrate?

Answer 1

Hint: The molecular formula is a chemical formula that specifies the total number of atoms of each element in each molecule of a substance.

Complete step-by-step answer:
\[{{\text{H}}_{\text{4}}}{\text{Ca}}{{\text{O}}_{\text{6}}}{\text{S}}\](\[{\text{CaS}}{{\text{O}}_{\text{4}}}{\text{ 2}}{{\text{H}}_{\text{2}}}{\text{O}}\]) is the formula for calcium sulfate dehydrate. It’s average mass is \[{\text{172}}{\text{.171 Da}}\]and monoisotopic mass is \[{\text{171}}{\text{.935455}}\,\,{\text{Da}}\]. These can be calculated form the molecular formula.

Calcium sulphate dihydrate (\[{\text{CaS}}{{\text{O}}_{\text{4}}}{\text{ 2}}{{\text{H}}_{\text{2}}}{\text{O}}\]) is mined or manufactured using more regulated chemical processes. The purity and shape of gypsum and its components vary, but the main characteristic of this material is that the water of hydration can be powered off with controlled heating. It then transforms into a substance with intriguing and practical properties. It can be combined with water or aqueous solutions and set to form a cement in certain ways.

Calcium sulphate dihydrate $(Ca_2+SO_4)$ is an ionic compound made up of\[{\text{C}}{{\text{a}}^{{\text{2 + }}}}\,{\text{and}}\,{\text{S}}{{\text{O}}_{\text{4}}}^{{\text{2 - }}}\]. The water molecules that are associated with crystallisation are known as waters of crystallisation, and they are tacked on to the material when it crystallises (from water). They could be removed after a long period of drying.

The mineral gypsum is classified as a calcium sulphate mineral with the chemical formula calcium sulphate dihydrate. Sulfate compounds are sulfuric acid salts or esters in which one or both hydrogens are replaced by a metal. In contrast to fluorides and oxides, which are usually insoluble in water, most metal sulphate compounds are readily soluble in water for uses such as water treatment. Organometallic forms are soluble in organic solutions, as well as aqueous and organic solutions in some cases.

Note: Calcium sulphate dihydrate is a hydrate and a calcium salt. It has calcium sulphate in it. In most cases, Calcium Sulfate Dihydrate is immediately available. Submicron and nanopowder types with high purity can be considered.
