1.what are the redox reaction
2.identify substance oxidixd agent and reducing agent in the following reaction
Answers
Answer:
redox is a type of chemical reaction in which the oxidation state of atoms are changed
redox reactions are characterized by the actual or formal transfer of electrons between chemical
species most often with one species undergoing
oxidation while another species undergo reduction
1.Redox is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the actual or formal transfer of electrons between chemical species, most often with one species undergoing oxidation while another species undergoes reduction.
2.MnO2+4HCl⟶MnCl2+2H2O+Cl2
Oxidation state: +4 −1 +2 0
Increase in oxidation state = Oxidation ⇒
As chlorine increases from −1⟶0⇒ (Oxidation of HCl)
Decrease in oxidation state = Reduction ⇒ As manganese decreases from +4→+2⇒ (Reduction of MnO2)⇒MnO 2 is reduced, HCl is oxidized, MnO2 is oxidizing agent, HCl is reducing agent.
