This scattering of light illuminates the path of the beam in the colloidal solution. (ii) Upon dissolved in ferric oxide solution, NaCl dissociates into Na+ and Cl- ions. Particles of ferric oxide solution are positively charged. Thus, they get coagulated in the presence of negatively charged Cl-ions.
