Hypo-osmosis refers to the state of a solution having a lower osmolarity compared to another solution.
In simpler terms, when comparing two solutions, the one with a lower concentration of solute particles (like salts or sugars) is considered hypoosmotic relative to the one with the higher concentration. The reference states, "...the solution with lower osmolarity is said to be hypoosmotic."
Here's a breakdown:
- Osmolarity: A measure of the solute concentration, defined as the number of osmoles (Osm) of solute per liter (L) of solution (osmol/L or Osm/L).
- Hypoosmotic: Having a lower osmolarity compared to another solution.
- Hyperosmotic: Having a higher osmolarity compared to another solution.
- Isoosmotic: Having the same osmolarity as another solution.
Example Scenario
Imagine two beakers of water.
- Beaker A: Contains water with 10 grams of salt.
- Beaker B: Contains water with 20 grams of salt.
In this scenario, Beaker A (with 10 grams of salt) is hypoosmotic relative to Beaker B (with 20 grams of salt). Beaker B is hyperosmotic relative to Beaker A.
