Question 15

The reaction of chlorine molecule with potassium iodide yields iodine molecule and potassium chloride. Write a balanced chemical equation for this reaction.


Cl2(g) + KI(s) → I(s) + KCl2(s)


Cl2(g) + KI2(s) → I2(s) + KCl2(s)


Cl2(g) + 2 K2I(s) → I2(s) + 2 K2Cl(s)


Cl(g) + KI(s) → I(s) + KCl(s)


Cl2(g) + 2 KI(s) → I2(s) + 2 KCl(s)
