Question 10 of 25 Consider this reaction Mgs 2H2O1 MgOH2s H2g What is the oxidation state of Mg in MgOH2s A 2 B 2 C 1 D 0 class=

Respuesta :

The oxidation number of Mg in Mg(OH)₂ is +2.

Hence, Option A is correct answer.

What is oxidation number?

The oxidation state, or oxidation number, is defined as the hypothetical charge of an atom if all of its bonds formed with different atoms were fully ionic. It indicates the degree of oxidation of an atom in a chemical compound. Conceptually, the oxidation state may be negative, positive or zero.

Oxidation number of OH = -1

Let us suppose the oxidation number of Mg = x

Charge on compound = 0

We can write

x + 2(-1) =0

x-2=0

x = 2

Thus from the above solution we concluded that The oxidation number of Mg is +2.

Hence, Option A is correct answer.
