What is the oxidation number of chromium in potassium dichromate?
potassium dichromate is K2Cr2O7. The oxidation number of Cr is -6. (Oxygen is -2, K is +1 so Cr must be -6)
What is the oxidation number of Cr is acidified potassium dichromate?
+6
What is the oxidation number for k2cro4?
Potassium's oxidation number is +1. Chromium's oxidation number is +6. Oxygen's oxidation number is -2.
What is the oxidation number of Fe and Cr in FeCr2O7?
The possible oxidation numbers for iron cations are +2 and +3. Oxygen in oxyanions is usually assigned an oxidation number of -2, producing a total negative charge of -14 for the seven oxygen atoms in a dichromate anion. If the iron cation has an oxidation number of +2, the two chromium atoms must have a total oxidation number of +12, which is possible when each chromium atom has an oxidation number of +6. An iron (III) cation would require the chromium atoms to have a non integral charge, which is not possible since electrons with half charges are not known. Therefore, the oxidation number of iron in the compound is +2 and the oxidation number for chromium is +6.
What is the name of the CrO4 ions?
If this compound existed it would be called chromium heptoxide. This would imply an impossibly high oxidation number for chromium. Chromium forms a number of oxides including Cr2O3 and a chromium(VI) oxide, chromium oxide peroxide.

Oxidation number of Cr in K2Cr2O7?
Potassium is the metal here and it has an Oxidation number of +1 in every compound because all Alkali Earth metals have an Oxidation Number of +1. (The other elements: Oxygen -2 and Chromium (Cr) +6)
What is oxidation number of chromium in Cr2O7?
The oxidation number of chromium in Cr2O7 is +7. The oxidation number of oxygen is -2, so 7 O atoms times -2 = -14. In order to balance the -14 on the oxygen atom, each chromium atom must have an oxidation number of +7, because 2 Cr atoms times +7 equals +14.
Potassium's minimum oxidation number?
the oxidation number for potassium is 1.
What is the oxidation number for Lead IV dichromate?
+4 for lead
What is the name for H2Cr2O7 acid?
H2Cr207 is also known as chromic acid.
What is the oxidation number of Cr in CrBr?
In CrBr (chromium monobromide) Cr would have an oxidation number of +1. This compound is not known perhaps you meant CrBr3, where chromium has an oxidation number of +3
What is the oxidation number of potassium in potassium meta periodete?
The chemical formula for potassium metaperiodate is KIO4. The oxidation number of potassium is +1.
