What are the physiological importance of protective colloids?
protective colloids are absorbed by solid particles,increase the strength of the double layer through hydrogen bonding and reduce the molecular interaction and aid in dispersion.they donot reduce the interfacial tension or the surface tension.
Are colloids heterogeneous or homogeneous?
Colloids are heterogeneous mixtures because they contain dispersed particles that are not dissolved and are larger than those found in true solutions, giving them the appearance of being mixed yet not fully dissolved.
What are the examples of negatively charged colloids?
Examples of negatively charged colloids include silica sols, bentonite clay suspensions, and latex particles. These colloids have surfaces that are negatively charged due to the presence of ions or functional groups that attract and repel other particles in the dispersion medium.
Which mixture scatter a beam of light that passes through them-a phenomenon called the Tyndall effect?
Colloids scatter a beam of light that passes through them, exhibiting the Tyndall effect. This is due to the particles in colloids being large enough to obstruct the path of light and scatter it in all directions, making the beam visible.
What is adsorptive properties?
ability of colloids is utilized in dyeing fabrics.
Are brownies colloids?
After my opinion they are not colloids.
Why do you destroy colloids?
Colloids are often destroyed or destabilized to separate their components for various applications, such as purification, clarification, or to prevent unwanted interactions. This can be achieved through methods like centrifugation, filtration, or adding flocculants, which promote the aggregation of particles. In some cases, destroying colloids is essential in industries like food processing or pharmaceuticals to enhance product quality or stability. Additionally, understanding colloid stability helps in applications like drug delivery and material science.
How are liquid-liquid colloids like mayonnaise are called?
These colloids are called emulsions.
What are the negative effects of colloids on the environment?
some colloids cause pollution in the environment...some colloids release cfc's that contributes to the ozone layer depletion...
What is the visibility of colloids?
colloids are not visible due to their tiny particle size, (when the colloid is stable).
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.
Is pizza a colloids?
no
What do gelatin milk and stick deodorant have in common?
They are all colloids.they are all colloids
Butter toothpaste paint whipped cream and frogs are all colloids?
Frogs are not colloids, they are amphibians.
How are solutions and colloids alike?
how are solutions suspensions and colloids alike
What has the author Monzer Fanun written?
Monzer Fanun has written: 'Colloids in drug delivery' -- subject(s): Colloids, Drug Delivery Systems, Drug delivery systems, Pharmacokinetics 'Colloids in biotechnology' -- subject(s): Colloids, Biotechnology, Therapeutic use, Surface-Active Agents
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.
