Dear SIR what are these compounds name(1) Na2C6H5O7.11H2O (2)NaKC4H4O6.4H2O
The name of a salt starts with the name of the cation (e.g., sodium or potassium) followed by the name of the anion (e.g., chloride or acetate). Salts are often referred to only by the name of the cation (e.g., sodium salt or ammonium salt) or by the name of the anion (e.g., chloride or acetate). The notation of hydrous compound • nH2O, where n is the number of water molecules per formula unit of the salt, is commonly used to show that a salt is hydrated. The n is usually a low integer, though it is possible for fractional values to exist. In a monohydrate n is one, in a hexahydrate n is 6 etc. (typical prefixes are mono, di, tri, tetra, penta, hexa, hepta, octa, nona, deca).
Also there is another variant of the nomenclature: the IUPAC(International Union of Pure and Applied Chemistry).
