Chromium | Uses, Properties, & Facts | Britannica
To obtain pure chromium, chromite is first treated with molten alkali and oxygen, converting all of the chromium to the alkali chromate, and the latter is dissolved in water and eventually precipitated as sodium dichromate, Na 2 Cr 2 O 7.The dichromate is then reduced with carbon to chromium sesquioxide, Cr 2 O 3, and that oxide in turn is reduced with aluminum to give …

Common Anions Table and Formulas List
Writing Formulas of Salts . Salts are compounds composed of cations bonded to anions. The resulting compound carries a neutral electrical charge. For example, table salt, or sodium chloride, consists of the Na + cation bonded to the Cl-anion to form NaCl. Salts are hygroscopic, or tend to pick up water.This water is called water of hydration.
