Hypertonic solution: A solution that contains more dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood. For example, hypertonic solutions are used for soaking wounds.
What is meant by hypertonic solution Class 9?
A hypertonic solution is one that has a higher solute concentration outside the cell than inside . If a cell is placed in a hypertonic solution, the cell will shrink due to water osmotically moving out. ... Thus water molecules move from inside to outside the cell.
What is meant by hypertonic and hypotonic solution?
A solution will be hypertonic to a cell if its solute concentration is higher than that inside the cell, and the solutes cannot cross the membrane. ... If the solute concentration outside the cell is lower than inside the cell, and the solutes cannot cross the membrane , then that solution is hypotonic to the cell.
What is hypertonic example?
A hypertonic solution is one which has a higher solute concentration than another solution. An example of a hypertonic solution is the interior of a red blood cell compared with the solute concentration of fresh water .
What are hypertonic solutions give example?
Common examples of hypertonic solutions are D5 in 0.9% normal saline and D5 in lactated ringers . The administration of hypertonic solutions should be monitored extremely closely, as they can quickly lead to fluid overload.
What is hypertonic condition?
Hypertonic solution: A solution that contains more dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood.
What is isotonic solution example?
A solution is isotonic when its effective mole concentration is the same as that of another solution. This state provides the free movement of water across the membrane without changing the concentration of solutes on either side. Some examples of isotonic solutions are 0.9% normal saline and lactated ringers .
What is an example of hypotonic solution?
Hypotonic Solution Examples
Hypotonic saline i.e., 0.45% sodium chloride or 0.25% sodium chloride with or without dextrose, 2.5% dextrose solution , etc are some of the examples of the hypotonic solutions that are hypotonic with respect to blood serum and are used as hypotonic intravenous solutions.
What is Cytolysis Class 9?
Cytolysis is the dissolution or disruption of cells , especially by an external agent.
What drinks are hypertonic?
- GU Roctane Energy Drink Mix.
- Lucozade Energy.
What are hypertonic solutions used for?
Examples of when hypertonic solutions are used include to replace electrolytes (as in hyponatremia), to treat hypotonic dehydration , and to treat certain types of shock. Solutions with a lower concentration of solutes than isotonic solutions are hypotonic.
What is hypertonic saline used for?
Clinicians use hypertonic fluids to increase intravascular fluid volume. Hypertonic saline can be utilized in the treatment of hyponatremia . Hypertonic saline and mannitol are both indicated to reduce intracranial pressure.
Is salt water a hypertonic solution?
Seawater is hypertonic . If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). ... Tapwater and pure water are hypotonic.
Does hypertonic shrink or swell?
A hypotonic solution causes a cell to swell, whereas a hypertonic solution causes a cell to shrink .
How does hypertonic saline work?
Hypertonic saline is a sterile saline solution of different concentrations, 3 percent, 3.5 percent, and 7 percent. It works by increasing the amount of sodium (salt) in the airways . Salt attracts water into the airways, which thins the mucus, making it easier to cough out.
What causes hypertonic?
The most common causes of hypertonic dehydration are diarrhea, high fever, and vomiting . These can lead to dehydration and a salt-fluid imbalance.
