Vedclass · Answer

(C) The colour of an electrolyte solution is determined by the presence of ions that can absorb specific wavelengths of light. Often,the colour is associated with the presence of transition metal ions (cations) or specific complex anions. Therefore,the colour depends on the nature of both the ions present in the solution. For example,in $CuSO_4$ solution,the blue colour is due to the $Cu^{2+}$ ion,but in other salts,the anion may also contribute to the colour.
