Question

Can a displacement reaction be a redox reaction explain with the help of an example

Answer 1

Yes, a displacement reaction is also aredox reaction, as it is always accompanied by oxidation-reduction. In this reaction, the more electronegative chlorine displaces iodine from its salt, potassium iodide. Chlorine is reduced from zero state to -1, and iodine is oxidised from -1 state to zero.

Answer 2

Yes, a displacement reaction is also a redox reaction, as it is always accompanied by oxidation-reduction.
Example-1
2 KI + Cl2 = 2KCl + I2
In this reaction, the more electronegative chlorine displaces iodine from its salt, potassium iodide. Chlorine is reduced from zero state to -1, and iodine is oxidised from -1 state to zero.

Example-2
Zn + H2SO4 = ZnSO4 + H2
Here, zinc is oxidised to +2 state from zero state, and hydrogen is reduced to zero state from +1 state. Zinc is more electropositive than hydrogen, and so it displaces hydrogen from the acid.
