Which property affects a Colligative?
Colligative Properties. The concentration of solute molecules and ions is a factor that determines the solution’s collectivative properties. However, it does not depend on the identity of the solution. These properties are called vapor pressure lowering and boiling point elevation. They also include freezing point depression and osmotic tension.
What factors affect the colligative property of a solution?
Important! The total amount of dissolved particle affects the colligative properties. Total dissolved particles=2 moles These calculations require that the molalitysolute be adjusted to reflect the actual number of particles. Entropy favors more mixing (less purity), so solvent tends to move toward higher concentrations.
How can we use the Colligative properties in daily life?
While colligative properties are usually considered to be for nonvolatile solvents, it also applies to volatile solvents (although it might be more difficult to calculate). The freezing point of water drops below the normal value for pure alcohol and pure water when it is mixed with alcohol (a volatile liquid).
Why do we need Molality?
While molarity refers to the volume of solution, molality refers to the amount of solvent. Molality is used to study the properties of solutions that are affected by temperature and vapor pressure. Because its value doesn’t change with temperature changes, Molality is used.
Which statement best describes three of the components of air?
Answer. Air is made up of a combination of gases. The main components of air are nitrogen, oxygen and argon.
Can water dissolve oxygen?
Although water molecules have an oxygen atom in them, it is not enough for aquatic organisms to live in natural waters. Water actually contains a small amount of oxygen. This is about 10 molecules per million.
Is my filter providing oxygen?
Anything that breaks down the water surface can help in circulating and aerating the water. If the water surface is being moved, then it is providing oxygen. As stated above, any surface agitating agent, such as wind, filter or pellets, will provide oxygen.
