Vedclass · Answer

(C) Bredig's arc method is a common technique used for the preparation of colloidal sols of metals like gold,silver,and platinum.In this method,an electric arc is struck between metal electrodes immersed in a dispersion medium (like water) stabilized by an ice bath.The intense heat of the arc vaporizes the metal (dispersion),and the cold surrounding medium causes the metal vapors to condense into colloidal-sized particles (condensation).Therefore,Statement-$I$ is correct,and Statement-$II$ is incorrect because the process involves both dispersion and condensation.

Consider the following statements:
Statement-$I$ : Gold sol is prepared by Bredig's arc method.
Statement-$II$ : Bredig's arc method involves both dispersion and condensation.
