Why does ferric hydroxide sol coagulate on addition of potassium sulphate ?
Dear student
Please find the solution to the asked query:
According to Hardy-Schulze law, higher the valency of the oppositely charged ion of the electrolyte being added, the faster will be the coagulation.
Therefore, when potasium sulphate is added the dispersed phase particles (colloidal particles) ,which are positively charged, takes up the negative ions which are the sulphate ions, and gets neutralized thus getting attracted to each other to form clumps and then coagulation takes place.
Hope this information will clear your doubts regarding the topic. If you have any other doubts please ask here on the forum and our experts will try to solve them as soon as possible.
