Types and Examples of Precipitation. In order to understand clearly what is precipitation, we will go through the different types and examples so that students can relate it with real life and get a clearer understanding. The types of precipitation are rain, fog drip, snow, sleet, hail, and graupel.
Define peptization. Peptization is the process responsible for the formation of stable dispersion of colloidal particles in the dispersion medium. In other words, it may be defined as a process of converting a precipitate into a colloidal sol by shaking it with dispersion medium in the presence of a small amount of electrolyte.

Define: Precipitation Medium Solution Verified by Toppr Precipitation: A chemical reaction in which two compounds in their aqueous state react to form an insoluble salt as one of the product. Acid+Base→Salt+Water Was this answer helpful?
Explain by giving examples. Solution. Verified by Toppr. Precipitation reactions occur when cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate. A precipitate is a solid that forms out of solution.

Crystallization is a chemical process in which the solid-liquid separation technique occurs. This process causes mass transfer of a solute from the liquid solution to a pure solid crystalline phase.
Give an example. Peptisation is the process of converting a precipitate into colloidal particles by adding suitable electrolyte. The electrolyte is known as peptising agent. It is stabilising agent. For example, the addition of small amount of dil. H Cl to stannic oxide precipitate gives a stable sol of stannic oxide. Was this answer helpful?
The iodoform test is used to determine whether a given unknown chemical contains carbonyl compounds (such as aldehydes and ketones) with the structure R-CO-CH3 or alcohols with the structure R-CH(OH)-CH3. Iodoform test is important to distinguish Ethanol from Methanol when Ethanol tests positive but Methanol does not.
