Question

The process of coagulation or loading can improve the effectiveness of sedimentation.

• A. True
• B. False

Answer 1

The correct option is A True

• The process of settling the heavy solids at the bottom is a mixture of a liquid and an insoluble solid 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$\mathrm{K}\mathrm{Al}{\left({\mathrm{SO}}_4\right)}_2.12{\mathrm{H}}_2\mathrm{O}$ is said to be a coagulating agent.

Therefore, the given statement is true.
