During dialysis
Updated On: May 17, 2024
- only solvent molecules can diffuse
- solvent molecules, ions and colloidal particles can diffuse
- all kinds of particles can diffuse through the semipermeable membrane
- solvent molecules and ions can diffuse
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The correct answer is D:solvent molecules and ions can diffuse
Concentration of salt and urea are kept low.Hemodialysis is a process by which the waste and water is removed from the blood with the help of an external filter that is known as dialyzer.It consists of a semi permeable membrane.The concentration of the solutes like potassium, phosphorus and urea are high in the blood in comparison to the dialysis solution, where it is very low.There is also replacement of the dialysate that ensures the concentration of the undesired solutes.

Applications of surface chemistry are:
Adsorption:
The process of attraction and aggregation of the molecules of a substance on the surface of a solid is known as adsorption. For Example, N2 adsorbs on the surface of activated charcoal
Two types of adsorption are:-
- Chemisorption: It is also known as Chemical Adsorption.
- Physisorption: It is also known as Physical Adsorption.
Corrosion:
The process through which the refined metals convert themselves into more stable compounds is known as corrosion.
Crystallisation:
The type of technique used in order to purify the substances to separate Solids from liquids is known as crystallisation.
Heterogeneous Catalysis:
The process wherein a catalyst is used in order to increase the rate of a chemical reaction is known as catalysis. The catalyst does not undergo any transformation and can be recovered in a chemically unchanged state.
There are two types of catalysis:-
- When the catalyst involved and the reacting substances are same states of matter or in the same phase, it is known as Homogeneous Catalysis.
- When the catalyst involved and the reacting substances are in different states of matter or different phases, it is known as Heterogeneous Catalysis.
