उत्तर
- Osmosis
- Water molecules are transported from their region of higher concentration (dilute solution or with a lower solute concentration) to their region of lower concentration (concentrated solution or with a higher solute concentration) via a semi-permeable membrane. This process is known as osmosis.
- Because it lets just the solvent particles pass through it rather than the solutes, the membrane is known as semipermeable.
- Osmosis will keep water molecules passing from a 5% sucrose solution to 10% sucrose solution over the semipermeable membrane. This will keep on until the water molecule concentration at both ends of the arrangement equal each other.
