प्रश्न

What do you understand by precipitation reaction? Explain with examples.

टीपा लिहा

उत्तर

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)
\[\ce{AgNO3(aq) + NaCI(aq) -> AgCI(s) ↓ + NaNO3(aq)}\]
The precipitate forms because the solid (AgCl) is insoluble in water.
