Question

2 example of redox reaction

Answer 1

2H2S+SO4----------->3S+2H2O

MnO2+4 HCL -----------> MnCl2+2H2O+Cl2

Answer 2

Answer

$\sf Zn + O_2 \rightarrow ZnO$

$\sf 2H_2 + O_2 \rightarrow 2H_2O$

$\sf Fe + N_2H_4 + H_2O \rightarrow Fe(OH)_2 + NH_3$

$\sf I_2 + Cl_2 + H_2O \rightarrow HIO_3 + HCl$

More Information

Redox reactions are type of reactions where both oxidation and reduction occurs.

Oxidation occurs when there is a

• Addition of oxygen (or a more electronegative element)
• Removal of Hydrogen (or a more electropositive element)
• Loss of electrons
• Gain in oxidation number.

Reduction occurs when there is a

• Removal of oxygen (or a more electronegative element)
• Addition of Hydrogen (or a more electropositive element)
• Gain of electrons
• Loss in oxidation number
