What is the oxidation state of chromium in K₂Cr₂O₇? A) 4 B) -2 C) 3 D) -4 E) 6

Question

Quizplus · Accepted Answer

The oxidation state of oxygen is -2 and the overall compound has a neutral charge, so the sum of the oxidation states of all the elements must be equal to zero.
Let x be the oxidation state of chromium.
Then, from the compound, we can write the following equation:
2K + 2S + 2Cr + O + 17O = 0
Simplifying and solving for x, we get:
x = +6
Therefore, the oxidation state of chromium in the compound is +6.
