Vedclass · Answer

(C) The $Chromyl$ $Chloride$ test is a specific qualitative test used to detect the presence of $Cl^-$ (chloride) ions in an inorganic salt. When a chloride salt is heated with potassium dichromate $(K_2Cr_2O_7)$ and concentrated sulphuric acid $(H_2SO_4)$,reddish-brown vapours of chromyl chloride $(CrO_2Cl_2)$ are evolved. These vapours,when passed into sodium hydroxide $(NaOH)$ solution,turn the solution yellow due to the formation of sodium chromate $(Na_2CrO_4)$.

The $Chromyl$ $Chloride$ test is performed to detect which of the following ions?
