The condensed, 27 character standard InChIKey (hashed version of the full standard InChI) of Chromium trioxide is: The InChIKey may allow easier web searches for Chromium trioxide, but it needs to be linked to the full InChI to get back to the original structure of the Chromium trioxide since the full standard InChI cannot be reconstructed from the InChIKey. The law of conservation of mass dictates that the quantity of each element given in the chemical formula does not change in a chemical reaction. Chromium trioxide is an inorganic compound having the chemical formula CrO3. It is named after its discoverer, Sir Ewart Jones. Chromium trioxide (also known as chromium(VI) oxide or chromic anhydride) is an inorganic compound with the formula CrO3. Thus, each side of the chemical equation must represent the same quantity of any particular element based on the chemical formula. It is the acidic anhydride of chromic acid, and is … The sodium salt is, however, around twenty times more soluble in water than the potassium salt (49 g/L at 0 °C) and its equivalent weight is also lower, which is often desirable. A concentrated solution of potassium dichromate in water. A mixture of chromium trioxide… It exists as a yellow hygroscopic solid, which can form tetra-, hexa-, and decahydrates. A chemical formula of Chromium trioxide can therefore be written as: The chemical formula of Chromium trioxide shown above is based on the molecular formula indicating the numbers of each type of atom in a molecule without structural information, which is different from the empirical formula which provides the numerical proportions of atoms of each type.
