Question

Osmotic pressure is the pressure that must be applied to a solution in order to prevent osmosis from the pure solvent. pressure that must be applied to a solution in order to cause osmosis to occur from me pure solvent. correction factor applied when a sample of gas is collected by water displacement. increase in vapor pressure when a solution is compared to a pure solvent, decrease in vapor pressure when a solution is compared to a pure solvent. A colloid consists of a medium analogous to the solvent in a solution, and large parties analogous to solute in a solution. These are called the_________and the__________, respective y. emulsifier; dispersed phase continuous phase; flocculant continuous phase; dispersion forces continuous phase; dispersed phase flocculant; emulsifier

Explanation / Answer

21. option a

Osmosis is the process of flow of solvent from the pure solvent side or low concentrated solution side to wards higher concentrated solution through a semipermable membrane.

Osmosis is caused due to difference in vapour pressures of the high concentrated solution and the less concentrated solution/ pure solvent (with higher vapor pressure).

The osmotic pressure is the excess pressure that need to be applied on the more concentrated solution to stop the osmotic flow of solvent from low concentrated solution /pure solvent.

22. Option D.

In a colloidal solution the the solvent is continuous phase( also known as dispersion medium) and the solute particles of colloidal size are dispersed throu out the continuous phase , thus are called dispersed phase.
