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.
Question. What do you mean by a precipitation reaction? 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.

When hydrogen sulphide gas is passed through a blue solution of copper sulphate, a black precipitate of copper sulphide is obtained and the sulphuric acid so formed remains in the ...
Give an example. Solution. Verified by Toppr. 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.

Answer – class9 crystallization is a process which helps to separate a pure solid from a solution in its crystal form. This is the in use to purify solid. For an example the salt we get from seawater can have many impurities in it. Hence, the process of crystallization is in use to remove these impurities. Share with friends.
