Question

Define respiration and precipitation reactions???​

Answer 1

When two reactants in solution react and one or more of the products is insoluble or forms a precipitate, the reaction is called a precipitation reaction. For example, when a solution of iron chloride and ammonium hydroxide are mixed, a brown precipitate of iron hydroxide is formed.

Respiration: The act of inhaling and exhaling air in order to exchange oxygen for carbon dioxide.
