Best Answer

In this kind of compound, oxygen is conventionally assigned an oxidation number of -2 and potassium an oxidation number of +1. For electrical neutrality, chromium must have an oxidation number of + 6, because 2(+1) + 2(+6) + 7(-2) is zero.

What is the oxidation number of chromium in K2Cr2O7?

The oxidation number of chromium in K2Cr2O7 is +6. Each potassium ion has an oxidation state of +1, and each oxygen atom has an oxidation state of -2. By setting up an equation based on the overall charge of the compound, it can be determined that chromium has an oxidation state of +6.


What is the oxidation of Cr in Ag2Cr2O7?

The oxidation state of chromium (Cr) in Ag2Cr2O7 is +6. This is because the total charge of the compound is zero, and the oxidation states of silver (Ag) and oxygen (O) are fixed. By assigning an oxidation state of +6 to oxygen, we can determine that chromium is in the +6 oxidation state.


Oxidation number of Cr in K2Cr2O7?

The oxidation number of chromium (Cr) in K2Cr2O7 is +6. This is because the total charge of the compound is 0, and each potassium (K) atom has an oxidation number of +1, and each oxygen (O) atom has an oxidation number of -2. Using these values, you can calculate the oxidation number of chromium to be +6.
