It is known that molecular formula of potassium dichromate is $K_{2}Cr_{2}O_{7}$ . As potassium has an oxidation state of +1 and an oxygen atom has an oxidation state of -2.

Let the oxidation state of chromium is x. Therefore, calculate the oxidation state of chromium as follows.

$K_{2}Cr_{2}O_{7}$ = 0 (as the molecule is neutral)

$(2 \times 1) + 2x + (-2 \times 7)$ = 0

2 + 2x - 14 = 0

x = +6

Thus, we can conclude that the oxidation state of the chromium in the potassium dichromate molecule is +6.
