Differbetween
The main difference between peptization and coagulation is that peptization involves the breakdown of a precipitate in order to form colloids whereas coagulation includes the formation of aggregates in a colloidal dispersion.

What is Peptization and coagulation?
Formation of sol from the precipitate by the addition of electrolyte is known as peptization. While the conversion of a sol into a precipitate is known as coagulation. It involves the neutralization of a sol particle to form a suspension and this represents the coagulation.
What is meant by Peptization?
Peptization or deflocculation is the process responsible for the formation of converting precipitate into colloid by shaking with it an electrolyte. This is particularly important in colloid chemistry or for precipitation reactions in an aqueous solution.
What is Peptization and example?
Peptization is the method of producing stable colloids using an electrolyte to split up and distribute a precipitate into the colloids. ... Example: When the ferric chloride is added to the precipitate of ferric hydroxide, the hydroxide precipitate transfer to the sol by absorbing ferric ions.
What is meant by peptization of colloidal sols?
Peptization is the process of formation of colloidal sol in which conversion of fresh precipitate into colloidal particles by shaking it with the dispersion medium with the help of a small amount of suitable electrolyte. The electrolyte which is added is called a peptizing agent.
What is the example of coagulation?
Examples of Coagulation
Milk proteins coagulate to thicken the mixture that forms yogurt. Blood platelets coagulate blood to seal a wound. Pectin gels (coagulates) a jam. Gravy coagulates as it cools.
What is coagulation explain with example?
Coagulation is the breakdown of a colloid by changing the pH or charges in the solution. Making yogurt is an example of coagulation wherein particles in the milk colloid fall out of solution as the result of a change in pH, clumping into a large coagulate.
How is Peptization prevented?
neutral solution. Nitric acid is added to the wash liquid to maintain a high electrolyte concentration and to prevent peptization during the washing step. (Peptization is the formation of a colloid by dispersion of a precipitate. Colloids pass through filter crucibles while precipitates don't.)
What is meant by Tyndall effect?
Tyndall effect, also called Tyndall phenomenon, scattering of a beam of light by a medium containing small suspended particles—e.g., smoke or dust in a room, which makes visible a light beam entering a window. The effect is named for the 19th-century British physicist John Tyndall, who first studied it extensively.
What is coagulation value?
“The minimum concentration of electrolyte in millimoles required to cause coagulation of one litre of colloidal solution is called coagulation value”. Additional Information: Coagulation is also known as flocculation or precipitation.
What is hardy Schulze rule?
The required amount of electrolyte for the coagulation of a definite quantity of colloidal solution is dependent on the valency of the coagulating ion (which is the ion that holds a charge which is opposite to the charge of the colloidal particles).
What are peptizing agents?
A product that enhances dispersion of a substance (such as clay) into colloidal form. Peptizing agents for drilling-mud clays are sodium carbonate, sodium metaphosphates, sodium polyacrylates, sodium hydroxide and other water-soluble sodium compounds, even common table salt, NaCl, if added at low concentration.
What is definition of precipitate?
1 : a substance separated from a solution or suspension by chemical or physical change usually as an insoluble amorphous or crystalline solid. 2 : a product, result, or outcome of some process or action. precipitate.
