what is the chemical formula of epsom salt
MgSO4·7H2O
title: Magnesium sulfate text: Magnesium sulfate Magnesium sulfate is an inorganic salt with the formula MgSO(HO) where 0≤x≤7. It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO·7HO), commonly called Epsom salt. The overall global annual usage in the mid-1970s of the monohydrate was 2.3 million tons, of which the majority was used in agriculture. Epsom salt has been traditionally used as a component of bath salts. Epsom salt can also be used as a beauty product. Athletes use it to soothe sore muscles, while gardeners use it to improve crops. It has a variety of other uses: for example, Epsom salt is title: Epsomite text: Epsomite Epsomite is a hydrous magnesium sulfate mineral with formula MgSO·7HO. Epsomite crystallizes in the orthorhombic system as rarely found acicular or fibrous crystals, the normal form is as massive encrustations. It is colorless to white with tints of yellow, green and pink. The Mohs hardness is 2 to 2.5 and it has a low specific gravity of 1.67. Epsomite is the same as the household chemical, Epsom salt, and is readily soluble in water. It absorbs water from the air and converts to hexahydrate with the loss of one water molecule and a switch to monoclinic structure. Epsomite forms title: Andrews Liver Salts text: GlaxoSmithKline. Andrews Liver Salts Andrews Liver Salts is a laxative and antacid for mild stomach complaints. It is sold as a powder which is added to water and mixed, creating effervescence, before being swallowed. The powder contains sugar; two antacids, sodium bicarbonate and citric acid; and a laxative, magnesium sulphate. The product is similar to Eno's salts and Kruschen salts, and a mild form of Epsom salts. The term "liver salts" or "health salts" is typically used for a laxative. Andrews Liver Salts was first sold from 1894, by William Henry Scott and William Murdoch Turner. Their business in the title: Friedel's salt text: Friedel's salt Friedel's salt is an anion exchanger mineral belonging to the family of the layered double hydroxides (LDHs). It has affinity for anions as chloride and iodide and is capable to retain them to a certain extent in its crystallographical structure. Friedel's salt general formula is: In the cement chemist notation, considering that and doubling all the stoichiometry, it can also be written as follows: Friedel's salt can also be considered as an AF phase in which chloride ions have replaced sulfate ions and is formed in cements initially rich in tri-calcium aluminate (CA).
