Question

What is the purpose of using osmosis to filter out the bad stuff?

1) To remove impurities from a solution
2) To separate different components of a mixture
3) To increase the concentration of a solute
4) To decrease the concentration of a solvent

Answer 1

Osmosis is used in water purification to filter out impurities by moving water through a semipermeable membrane, separating it from dissolved solids.

Step-by-step explanation:

The purpose of using osmosis to filter out impurities is to remove impurities from a solution. Reverse osmosis (RO) is a process where water is moved through a semipermeable membrane from a more concentrated solution to a less concentrated solution by applying pressure that is greater than the osmotic pressure. This method is widely used in reverse osmosis water purification systems to provide clean water. The semipermeable membrane allows water molecules to pass through while blocking most dissolved solids (impurities), thus purifying the water.
