Redox reactions are reactions during which electron transfer takes place. Here

magnesium atom transfers two electrons one each to the two chlorine atoms.

i) What are the products of this reaction?

ii) Write the balanced equation for the complete reaction.

iii) Which element is being oxidized?

iv) Which element is being reduced?

v) Write the reduction part of the reaction.

Answer :

(i) The product of this reaction is – MgCl₂

(ii) The balanced equation for the complete reaction is : -

Mg_(s) + Cl_2(g) → MgCl_2(s)

(iii) In this reaction magnesium is the element which is being oxidised as it is losing two electrons and gets converted to a stable cation Mg²⁺.

(iv) In this reaction chlorine is the element which is getting reduced as the two chlorine atoms accepts one electron each and gets convert into anion Cl^-.

(v) Reduction part of the reaction is : -

2Cl + 2e^-→ 2Cl^-
