Question

Find out the oxidising agent (oxidant) and reducing agent in the following chemical reactions:
i) V2O5 + 5Ca -----> 2V + 5CaO
ii) Pb3O4 + 8HCl -------> 3PbCl2 + Cl2 + 4H2O
iii) CuO + H2----------> Cu + H2O​

Answer 1

Sulfur is called the oxidizing agent. The zinc causes the sulfur to gain electrons and become reduced and so the zinc is called the reducing agent. The oxidizing agent is a substance that causes oxidation by accepting electrons; therefore, its oxidation state decreases.22-Aug-2019

Substance is: Reduced

Oxidation State: Decreases

# of Electrons: Gained
