Answer: Oxidation is defined as the reaction in which there is loss of electrons. It is accompanied by increase in oxidation number.
[tex]Zn\rightarrow Zn^{2+}+2e^{-}[/tex]
Zinc in solid state has oxidation number of zero and on losing electrons changes to [tex]Zn^{2+}[/tex] with oxidation number of +2.
Reduction is defined as the reaction in which there is gain of electrons. It is accompanied by decrease in oxidation number.
[tex]2H^++e^{-}\rightarrow H_2[/tex]
Hydrogen ions with +1 oxidation state gains electrons and converts to molecular hydrogen with oxidation state of zero.
In the given redox reaction, both oxidation and reduction takes place. They go hand in hand.
[tex]Zn+H_2SO_4\rightarrow ZnSO_4 +H_2[/tex]
Zinc converts to [tex]Zn^{2+}[/tex] and gets oxidized. [tex]H^+[/tex] gains electron and convert to [tex]H_2[/tex].
Answer:
Oxidation is the loss of electrons.
Reduction is the gain of electrons.
Oxidation increases the oxidation number.
Reduction decreases the oxidation number.
In an oxidation-reduction reaction, the electrons from the oxidized atom or ion are transferred to the atom or ion that is reduced.
