Question

What is the oxidation state of Ga in GaCl2???

Answer 1

$\large{\sf GaCl_{2}}$

Let assume oxidation of Ga is x

We know Oxidation state of Cl is -1

so,

$\large{\sf x+2×(-2)=0}$

$\large{\sf x = +4}$

Hence.

Oxidation state of Ga is +4

Answer 2

The oxidation state of Ga in $GaCl_{2}$ is +2.

Explanation:

• Oxidation state is defined as the state which depicts either a positive or negative number on an element.

• For a compound to be neutral in nature there will occur exchange of oxidation state of the combining atoms. This will also contribute to the stability of the compound.

• Gallium (Ga) can have an oxidation state of +1, +2, and +3. And, oxidation state of chlorine is -1. So, according to cross multiplication method when 2 chlorine atoms are attached to Ga then oxidation state of Ga is +2.
