Why lyophilic is more stable than lyophobic?
Lyophilic colloids have a strong affinity for the dispersing medium, forming stable interactions that prevent agglomeration. In contrast, lyophobic colloids lack affinity for the dispersing medium, leading to weaker interactions and increased tendency for precipitation or coagulation, making them less stable.
Why only lyophobic colloids show tyndall effect?
Lyophobic colloids have particles that repel the dispersion medium, preventing them from easily mixing. This causes the particles to scatter light, which is why they exhibit the Tyndall effect. In lyophilic colloids, the particles have an affinity for the dispersion medium and do not scatter light as effectively.
When colloids are filtered do they leave residue?
Yes, colloids can leave a residue when filtered. Colloids are larger particles that can be trapped by the filter, resulting in a residue left behind after filtration.
Are all colloids negatively charged?
No, not all colloids have a negative charge. Colloids can have a positive, negative, or neutral charge depending on the type of particles present in the dispersion and the interactions between those particles.
Can colloids conduct current?
no. not really
What is lyophillic colloids?
Lyophilic collids molecules are more attracted to the dispersion medium then the particles themselves there by coagulation does not takes place

Which is more stable a iyophilic or a iyophobic colloids why?
lyophilic solution is more stable cause it is attracted while liophobic are stabilised by agents like detergents
How can colloids be destroyed?
Colloids can be destroyed by heating them or adding an electrolyte in order to destroy them. By adding a small amount of a electrolyte, a colloid can be coagulated. Electrophoresis may be another method to destroy a colloid.
What are lyophilic colloids?
Lyopobic colloid is a colloidal dispersion whereby the dispersed phase is solvent hating .i.e little interaction between the dispersed phase and the continuous phase. Lyophobic colloidal particles are not readily solvated because the continuous phase prefer to interact with one another than be involved in solvating the dispersed particles. Lyophobic colloidal dispersion does not form spontaneously when the dispersed particles and the continuous phase are brought together. The dispersed particles will tend to aggregate i.e thermodynamically favourable. However this is not pharmaceutically favourable. Dispersion method and condensation method are two methods involved in manufacturing lyophobic colloids. If the continuous phase is water, it is also called hydrophobic colloids.
What are the three types of colloidal system?
The three types of colloidal systems are sol, gel, and emulsion. In a sol, solid particles are dispersed in a liquid; in a gel, a network of solid particles is formed within a liquid; and in an emulsion, two immiscible liquids are dispersed in each other with the help of an emulsifying agent.
How are the properties of colloids utilized in technology?
Medicines in colloidal form are easily adsorbed by the body tissues and hence are more effective, biological sciences are with numerous colloidal systems, including cell membranes, viruses, bacteria, DAN, proteins... colloids play a role in the semiconductor industry, memory chips, and micro-processors, Polymers, or macromolecules, in solution are lyophilic colloids...
What is the antonym for aerobatic?
Coagulated. Such as all the debri coagulated to the bottom of the tank.
How can coagulated be use in a sentence?
I have stopped bleeding because my blood has coagulated.
How do you use coagulated in a sentence?
The spilled water coagulated quickly on the frozen floor.
Are brownies colloids?
After my opinion they are not colloids.
