What is the oxidation state of chromium in K₂Cr₂O₇?

Question

Quizplus · Accepted Answer

Chromium is bonded with Oxygen which has an oxidation state of -2, and it is also bonded with two sulfurs with an oxidation state of -2. The sum total of the oxidation state of all the elements is equal to zero for the compound. So, using algebra, we can find the oxidation state of Chromium:

Let x be the oxidation state of Chromium.

K(S1-)1U1B12(S1-)1U1B0Cr(x)S1-)1U1B12(S1-)1U1B0O(-2)S1-)1U1B17(S1-)1U1B0 = 0

Solving for x,

x = +6

Therefore, the oxidation state of Chromium is +6.
