Question

The pair of the compound in which both the metals are in the highest . Possible oxidation state is

Answer 1

Answer:

Oxidation state of a metal is the number assigned to a metal element in a chemical combination which represents the no. of electrons lost by an atom of that metal element in a compound.

Examples of metals taking higher oxidation states in a reaction are :

Chromium (Cr) and Manganese (Mn) .

Manganese oxidation states are :

+7 (the highest oxidation state) and +2 (the lowest oxidation state)

Chromium oxidation states are :

+6 (the highest oxidation state) and +2 (the lowest oxidation state)

Examples of two compounds with these two metals in their highest oxidation states are:

KMnO₄ ( Potassium Permanganate) where the oxidation state for Mn is +7.

CrO₂Cl₂ ( Chromyl Chloride) where the oxidation state of Cr is +6.
