Vedclass · Answer

(D) When chlorine water is added to a solution containing iodide ions $(I^-)$,iodine $(I_2)$ is liberated. $2KI + Cl_2 \rightarrow 2KCl + I_2$ This liberated $I_2$ dissolves in the chloroform $(CHCl_3)$ layer,imparting a violet colour. Upon adding excess chlorine water,the liberated $I_2$ is further oxidized to iodate $(IO_3^-)$,which is colourless. $I_2 + 5Cl_2 + 6H_2O \rightarrow 2HIO_3 + 10HCl$ Thus,the disappearance of the violet colour confirms the presence of iodide ions.
