Question

In the reaction between Pb3 and HCl the number of moles of HCl oxidized by a mole of Pb3O4​

Answer 1

Answer:

This is an oxidation-reduction (redox) reaction:

3 Pb8/3 + 2 e- → 3 PbII

(reduction)

2 Cl-I - 2 e- → 2 Cl0

(oxidation)

Pb3O4 is an oxidizing agent, HCl is a reducing agent.

Answer 2

Answer:

This is an oxidation- reduction (redox) reaction.

Explanation:

• Oxidation -reduction reaction is known as redox reaction.
• It is a type of chemical reaction in which the oxidation states of substance change.
• Oxidation is the loss of electrons or an increase in the oxidation state of chemical or atoms within it.
• Oxidation involves the addition of oxygen to a substance, reduction is removal of oxygen from a substance.

In the reaction between Pb3 and HCl the number of moles of HCl oxidized by a mole of Pb3O4​ is oxidation- reduction reaction.
