m​

Answer 1

Answer:

This can occur when solutions containing ionic compounds are mixed and an insoluble product is formed. The identity of the precipitate can often be determined by examining solubility rules. 

It also occurs in single displacement when one metal ion in solution is replaced by another metal ion. Notice the new solid forming on the bottom of the tube.

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. Precipitation reactions can help determine the presence of various ions in solution.
