Question

what are precipitation reaction?explain with the help of an example

Answer 1

Answer:

Precipitation reactions occur when cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate. A precipitate is a solid that forms out of solution.

A common example is that of the mixing of two clear solutions: Silver nitrate (AgNO3) and sodium chloride (NaCl):

AgNO3aq)+NaCl(aq)→AgCl(s)↓+NaNO3 (aq)

Answer 2

Answer:

PRECIPITATION REACTION IS A DOUBLE DISPLACEMENT REACTION IN WHICH A PRECIPITATE IS FORMED.

Explanation:

EG:-Pb(NO³)²+2NaL-------Pbl²+2NaNo³
