The halogen that is most easily reduced is

Chlorine is manufactured by

When chlorine gas is passed through an aqueous solution of a potassium halide in the presence of chloroform,a violet colouration is obtained. On passing more of chlorine water,the violet colour disappears and the solution becomes colourless. This test confirms the presence of ........... in the aqueous solution.

The bond energy of $Cl_2, Br_2$ and $I_2$ follows the order:

Which of the following halogens is obtained from Caliche?

Why are halogens strong oxidising agents?
