Answer 2

Answer:

The compound which chromium has +6 oxidation state

$\mathrm{K}^{\oplus}\left[\mathrm{CrO}_3 \mathrm{Cl}\right]^{\ominus}$ : Oxidation state of Cr = +6

$\mathrm{CrO}_5$ : Oxidation state of  Cr = +6 (Two peroxo linkage)

Explanation:

What is meant by oxidation state?

An atom's oxidation state can be described as the potential charge it would carry if all of its bonds to other atoms were entirely ionic in nature.

While chromium can exist in a variety of oxidation states, the +3 and +6 states are the ones that are most frequently seen in its compounds.

Let x be the oxidation number of chromium in $\mathrm{KCrO}_3 \mathrm{C} 1$

The oxidation numbers of potassium, chlorine and oxygen exists +1, -1 and -2 respectively.

The total number of atoms in a neutral atom have an oxidation number of zero. As a result, the sum of the oxidation numbers of one potassium atom, one chromium atom, one chlorine atom, and three oxygen atoms will be zero.

Calculate the oxidation number of chromium in $\mathrm{KCrO}_3 \mathrm{C} 1$

⇒ +1 + x + 3(-2) - 1 = 0

⇒ 1 + x - 6 - 1 = 0

⇒ x - 6 = 0

⇒ x = +6

$\mathrm{K}^{\oplus}\left[\mathrm{CrO}_3 \mathrm{Cl}\right]^{\ominus}$ : Oxidation state of Cr = +6

$\mathrm{CrO}_5$ : Oxidation state of  Cr = +6 (Two peroxo linkage)
