Solution
The correct option is A True
The process of settling the heavy solids at the bottom of a mixture is called sedimentation.
When solid particles present in a liquid are not sufficiently heavy, they do not settle easily.
This process of improving the settling property of solid particles by the addition of special chemicals such as alum is called coagulation or loading. Alum is said to be a coagulating agent.
