Many chemical reactions occur in our daily lives. Common examples of such reactions are burning, corrosion, cooking of food and digestion. One important class of chemical reactions are precipitation reactions. In such reactions, two different soluble salts (which are in aqueous solutions) combine to form two products. One of these products is insoluble in the solution and is precipitated out (and is, therefore, referred to as the ‘precipitate’).

Answer 2

Answer:

A precipitation reaction refers to the formation of an insoluble salt when two solutions containing soluble salts are combined. The insoluble salt that falls out of solution is known as the precipitate, hence the reaction's name.
