how are associated colloids different

-Associated colloids are different from multimolecular and macromolecular colloids in the way as follows: Substances when dissolved in a medium at low concentrations behave as normal electrolytes but at higher concentration aggregate to form a micelle are associated colloids.

How is associated colloids different from other colloids?

Multimolecular colloids are formed by the aggregation of a large number of simple molecules, macromolecular colloids consists of macromolecules having size in the colloidal range. On the other hand, associated colloids also called micelles, are generally electrolytes. They exist as ions at low concentration.

How are associated colloids different from macromolecular colloids give one example of each type?

Solution : Associated colloids are formed by electrolytes so that they are dissociated into ions and these ions associate together to form ionic micelles whose size lies in the colloidal range, e.g. soaps. ... Macromolecular colloids - due to large size of the molecules themselves.

What is associated colloid?

Associated Colloids : The substances which when dissolved in a medium at low concentrations behave as normal, strong electrolyte but at higher concentration exhibit colloidal state prodperties due to the formation of aggereated particles are called associated colloids.

What are associated colloids give examples?

The formation of the micelles occurs above a particular temperature called the Kraft temperature (Tk) and also above a specific concentration called the critical micelle concentration. These colloids can be reverted by diluting it. Examples of some associated colloids are soaps and synthetic detergents.

What is Multimolecular colloid?

Multimolecular colloids: A large number of atoms or smaller molecules (diameter <1 nm) of a substance on dissolution aggregate together to form species having size in the colloidal range.

How are colloids classified on the basis of?

Colloids can be classified on various bases: On the basis of the physical state of the components (by components we mean the dispersed phases and dispersion medium.) . Depending on whether the components are solids, liquids, or gases, we can have eight types of colloids. Was this answer helpful?

Which of the following is macromolecular colloid?

Solution : Starch and cellulose are high molecular mass molecules.

What is the difference between Sol and gel?

Sol: The liquid state of a colloidal solution is called the sol. Gel: The solid or semi-solid (Jelly like) stage of a colloidal solution is called the gel. The present post discusses about the Difference between Sol and Gel. Definition: The liquid state of a colloidal solution is called sol.

What is the cause of Brownian motion?

Brownian movement arises because of the impact of the molecules of the dispersion medium with the colloidal particles. Since the impacts of the molecules of the dispersion medium on the colloidal particles are unequal (i.e. unbalanced bombardment), the result is zig-zag motion.

What are 5 examples of colloids?

Colloids are common in everyday life. Some examples include whipped cream, mayonnaise, milk, butter, gelatin, jelly, muddy water, plaster, colored glass, and paper. Every colloid consists of two parts: colloidal particles and the dispersing medium.

What are the 5 types of colloids?

Combining different substances can result in five main types of colloid mixtures: aerosols, foams, emulsions, sols and gels. Some of these colloids exist naturally in the world, while others are man-made products.

Which of the following is a colloid?

Milk, ice cream and blood are colloids while urea is a true solution.
