Metals like silver and copper can be obtained in the colloidal state by?
=> Dialysis
Answer:
Bredig's arc approach or electric disintegration is a technique of education of colloidal answer, of metals which includes gold, silver or platinum. This approach includes each dispersion and condensation.
Explanation:
Colloidal answers of metals are normally organized with the aid of using Bredig's arc approach wherein an arc is struck among the metallic electrodes below the floor of water containing a few stabilizing retailers which includes a tune of KOH. How is silver colloidal answer made?
In the present day study, silver colloids are organized with the aid of using a two-step discount of silver nitrate at high (100°C) and low (92°C) temperatures withinside the presence of sodium citrate. These uniformly sized silver debris have a mean length of forty seven nm and a relative general deviation of 14%. handiest copper and silver reacts if pressurised. Gold, and Platinum do now no longer react with something they're known as noble metals. Silver reacts with only some elements.so, copper and silver are observed in loose state.
