Question

define perception. explain an activity showing precipitation in reacting Na²SO⁴ with bacl² what is the nature of chemical reaction

Answer 1

Answer:

These two solutions react to form a white insoluble precipitate. 

BaCl2+Na2SO4→2NaCl+BaSO4↓ 

This is a double displacement reaction as the two compounds exchange their ions to form two different compounds.

Explanation:

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’).
