Explain the terms semipermeable membrane, osmosis and osmotic pressure. What are isotonic solutions?
Explain with one example.
Answers
Answer:
An isotonic solution is one that has the same concentration of solutes both inside and outside the cell. A hypertonic solution is one that has a higher solute concentration outside the cell than inside. A hypotonic solution is the one that has a higher solute concentration inside the cell than outside
Answer:
The given terms are explained below.
Explanation:
Semipermeable membrane : It is a biological, synthetic or polymeric membrane and taken in use for the removal of unwanted materials from solution. It allows the passage of only certain particles from it due to the pore size.
Osmosis : The process in which solvent moves spontaneously from a region of lower solvent concentration towards the region of higher water concentration is known as osmosis. Solvent passess through a semipermeable membrane.
Osmotic pressure: The minimum pressure required to stop the spontaneous flow of solvent is known as osmotic pressure.
Isotonic solution : When the concentration of the solution inside and outside of the cell is same, it is known as isotonic solution. In this condition , there is no net movement of solvent. Example: If a resin is put in an isotonic solution it will neither swell nor sink.
