Question

Can displacement reaction be redox reaction . Explain with help of an example

Answer 1

Yes, a displacement reaction is also a redox 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.
Example-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.
