In the reaction equation bro-3(aq) br-(aq) + bro-4(aq), how many oxidation states does the disproportionate substance have throughout the reaction? 0 1 2 3

Answer : The correct answer is 3.

Explanation :

The given chemical reaction is,

In a disproportionate reaction, disproportionate substance is a single substance which is oxidized as well as reduced.

The oxidation state of Br in is (+5).

The oxidation state of Br in is (-1).

The oxidation state of Br in is (+7).

In the given chemical reaction, is getting reduced to and is getting oxidized to . So, bromine is a disproportionate substance.

That means the bromine is present in three oxidation states.

Therefore, three oxidation states of the disproportionate substance have throughout the reaction.

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
