What is molecular formula of CaSO4?
What is CaSO4 compound name?
Calcium sulfate, CaSO4, is a naturally occurring calcium salt. It is commonly known in its dihydrate form, CaSO4∙2H2O, a white or colourless powder called gypsum. As uncalcined gypsum, the sulfate is employed as a soil conditioner.
How is anhydrite formed?
A member of the evaporite group of minerals and the soft rock comprising anhydrite formed by precipitation of calcium sulfate from evaporation of seawater. Anhydrite can also form through the dehydration of gypsum, another sulfate mineral found in evaporites. Anhydrite may occur as a caprock above salt domes.
What is the chemical formula of anhydrite?
Anhydrite, or anhydrous calcium sulfate, is a mineral with the chemical formula CaSO4. It is in the orthorhombic crystal system, with three directions of perfect cleavage parallel to the three planes of symmetry.
Is CaSO4 acidic or basic?
CaSO4 , K2CO3 are basic salts.
Where is anhydrite used?
Anhydrite is one of the major minerals in evaporite deposits; it also is present in dolomites and limestones, and as a gangue mineral in ore veins. It is used in plasters and cement as a drying agent.
What is corundum chemical formula?
Corundum is an aluminum oxide mineral of the oxides and hydroxides group, with structural formula Al2O3.
What is the pH of CaSO4?
Calcium sulfate is only slightly soluble in water. When it does dissolve, the ions are spectator ions. This means that they do not interact with water molecules in a way that significantly changes the pH. The pH of a saturated solution of calcium sulfate is 7.7, close to that of pure water.
Is MgSO4 basic or acidic?
MgSO4 —This salt was formed from the reaction of a strong base, magnesium hydroxide, with strong acid, sulfuric acid. This reaction results in a neutral salt. 3.
