Chromic ion formula
WebChromate is an ion that contains one chromium atom (in its +6 oxidation state) and four oxide atoms. Its formula is CrO 4.Its overall charge is -2. Dichromate is similar, but it contains two chromium atoms and seven oxide atoms (therefore, Cr 2 O 7).. Chromate and dichromate are strongly oxidizing in acidic conditions, but weakly oxidizing in basic … WebDec 27, 2024 · So, polyatomic ion SO 4-2 will be placed inside parenthesis. Cr is placed outside the parentheses as it is not a polyatomic ion. So, to arrive at the formula of Chromium III Sulfate, we will interchange the charges of ions Cr +3 and SO 4-2 to get Cr 2 and (SO 4) 3. When we write the two together we get Cr 2 (SO 4) 3.
