Text Solution

AI Generated Solution

To determine which electrolyte is most effective for the coagulation of `Fe(OH)3` sol, we will follow these steps: ### Step 1: Identify the nature of the sol `Fe(OH)3` is a positively charged sol. ### Step 2: Understand the coagulation process According to the Hardy-Schultz law, the coagulation power of an electrolyte is directly proportional to the valency of the ion that causes coagulation. For a positively charged sol, we need an anion (negatively charged ion) with a higher valency to effectively coagulate the sol. ...
