Question

Answer

Sedimentation - this is the process by which allows particles to settle down at the bottom.

Answer

Sedimentation

Answer

Filtration

Answer

Understanding Sedimentation
Sedimentation is an important process in separating insoluble particles from a liquid solution. Here’s how it works and why option 'C' is the correct answer.
What is Sedimentation?
- Sedimentation is the process by which solid particles settle out of a liquid due to the force of gravity.
- It occurs when a mixture is allowed to stand undisturbed for a period of time, allowing heavier particles to fall to the bottom.
Steps in Sedimentation:
1. Preparation: A mixture containing insoluble particles is placed in a container.
2. Time: After some time, the particles begin to settle at the bottom of the container.
3. Separation: The clear liquid above the settled particles can then be carefully removed or decanted.
Importance of Sedimentation:
- Water Treatment: It is widely used in water purification to remove impurities.
- Natural Processes: Sedimentation occurs naturally in rivers and lakes, helping to maintain clean water bodies.
Contrast with Other Processes:
- Filtration: This involves passing the mixture through a filter, separating solid particles immediately, rather than allowing them to settle.
- Decantation: This is the process of gently pouring off the liquid from the settled solids, but it follows sedimentation.
In summary, sedimentation is the key process that allows insoluble particles to settle down in a solution, making option 'C' the correct choice.

Answer

The process which allows insoluble particles to settle down in a solution is called sedimentation.
Sedimentation is a physical process in which particles suspended in a liquid settle down at the bottom of the container due to gravity. Here is a detailed explanation of sedimentation:
1. Definition:
- Sedimentation is the process by which solid particles separate from a suspension and settle at the bottom of a liquid.
2. Process:
- When a suspension is left undisturbed, the force of gravity causes the solid particles to settle down at the bottom of the container.
- The settling process is influenced by the size, shape, and density of the particles, as well as the viscosity of the liquid.
- The larger and denser particles settle faster, while smaller and lighter particles take longer to settle.
3. Importance:
- Sedimentation is an important process in various industries, such as water treatment, wastewater treatment, and mining.
- In water treatment plants, sedimentation is used to remove suspended solids from the water, making it clearer and safer to drink.
- In mining operations, sedimentation is used to separate valuable minerals from the ore.
4. Differences from other processes:
- Filtration is a process that separates solid particles from a liquid or gas by passing it through a filter medium. It is different from sedimentation because it involves the use of a physical barrier (filter) to separate the particles.
- Decantation is a process in which a liquid is carefully poured off from a mixture, leaving the solid particles behind. It is different from sedimentation because it involves the separation of liquid and solid phases by pouring.
In conclusion, sedimentation is the process in which insoluble particles settle down in a solution due to gravity. It is an important process used in various industries for separation and purification purposes.
