What is the difference between hypertonic and hypotonic?
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 a cell is placed in a hypotonic solution, there will be a net flow of water into the cell, and the cell will gain volume.
What is hypotonic solution with diagram?
Isotonicity and Examples
| Tonicity | Definition | Examples |
|---|---|---|
| Hypotonic | Solution has less solute than the cell | Distilled water |
| Hypertonic | Solution has more solute than the cell | Ocean water |
| Isotonic | Solution and the cell have equal concentrations of solute | 0.9% saline |
What is the difference between a hypotonic solution and a hypertonic one?
1. Hypotonic solutions have less solutes and more solvent while hypertonic solutions have more solutes and less solvent. 2. Hypotonic solutions cause the cell to swell because it promotes shifting of water into it while hypertonic solutions cause the cell to shrink because it pulls the water out of the cell.
Which solution is hypertonic and hypotonic?
In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration is hypertonic, and the solution with the lower solute concentration is hypotonic. Solutions of equal solute concentration are isotonic. The first sugar solution is hypotonic to the second solution.
What is example of hypertonic?
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.
How do you remember tonicity?
You can do it by remembering the following: Hypotonic fluids are hippotonic cells because all the fluid goes into the cell causing it to swell. Hypertonic fluids are for skinny cells because the fluid goes out of the cell, making it skinny. When people are hyper, they become skinny.
What is the tonicity of water?
Tonicity is a measure of the effective osmotic pressure gradient; the water potential of two solutions separated by a semipermeable cell membrane. Tonicity depends on the relative concentration of selectively membrane permeable solutes across a cell membrane which determine the direction and extent of osmotic flux.
What is osmosis with diagram?
Osmosis is the diffusion of water across a partially permeable membrane from a dilute solution (high concentration of water) to a concentrated solution (low concentration of water). In the diagram, the concentration of sugar is initially higher on the right side of the membrane.
What is an example of a hypertonic solution?
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 the types of hypertonic solutions?
Common Hypertonic Solutions. Here are a few examples: Saline solution, or a solution that contains salts, is hypertonic. This type of hypertonic solution is extremely common. For instance, saline solutions are often used in the medical field, as well as in contact lens fluid, to help keep contact lenses clean and free from dust and pollutants.
When would you give a hypertonic solution?
These solutions are very useful when the cells have water intoxication, when they have been in a hypotonic medium for a long time and they are swollen. Therefore, an administration of hypertonic solution causes a cellular dehydration and would be beneficial for the cell.
When to give hypotonic solution?
Hypotonic solution: A solution that contains fewer dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood. Hypotonic solutions are commonly used to give fluids intravenously to hospitalized patients in order to treat or avoid dehydration.
