Hydrated chromium(III) sulfate, Cr 2 (SO 4) 3 ·18H 2 O, (CAS #13520-66-6) is a violet solid that readily dissolves in water to give the metal aquo complex, [Cr(H 2 O) 6] 3+. The formula of this compound can be written more descriptively as [Cr(H 2 O) 6 ] 2 (SO 4 ) 3 ·6H 2 O. Six of the eighteen water molecules in this formula unit are water ...
The oxidation states are also maintained in articles of the elements (of course), and systematically in the table {{Infobox element/symbol-to-oxidation-state}} See also [ edit ]
A large number of chromium(III) compounds are known, such as chromium(III) nitrate, chromium(III) acetate, and chromium(III) oxide. [8] Chromium(III) can be obtained by dissolving elemental chromium in acids like hydrochloric acid or sulfuric acid , but it can also be formed through the reduction of chromium(VI) by cytochrome c7 .

The number indicates the degree of oxidation of each element caused by molecular bonding. In ionic compounds, the oxidation numbers are the same as the element's ionic charge. Thus for KCl, potassium is assigned +1 and chlorine is assigned -1. [4] The complete set of rules for assigning oxidation numbers are discussed in the following sections.
The MLB world lost its all-time leader in stolen bases on Saturday with the death of Rickey Henderson, who was among baseball's brightest stars of the 1980s and '90s.. Henderson will always be ...
Hours after Joe Biden stepped aside in the 2024 presidential campaign and backed Kamala Harris, large and small donors began digging back into their pockets.
He was 2 of 3 on the day already, and would have been facing as much as a 52-yard kick to win the game. That’s a hell of a lot of pressure to put on a redshirt freshman.
