Question

What is precipitation reaction? give one example of it which also double displacement reaction?

Answer 1

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.

one example of it which also double displacement reaction is-

AgNO3 (aq) + KCl (aq) → AgCl (s) + KNO3(aq)

Here, AgCl ( silver nirate) is the white precipitate.

Answer 2

Answer:

In the above reaction silver nitrate and potassium chloride are getting displaced to silver chloride and potassium nitrate. Silver chloride is insoluble therefore it precipitates.
