Question

The precipitate formed in a precipitate reaction is a/an _____ compound.

Answer 1

The precipitate formed in a precipitate reaction is an insoluble compound because of which it settles at the bottom of the beaker and is separated from the rest of the solution by the process of filtration.

It separates out in the form of precipitates because it is insoluble in the solution.

Precipitates are formed as a result of the double displacement reaction.

Example of precipitation reaction: In this reaction, precipitates of Barium sulphate are formed.

• $$\begin{gathered} {\mathrm{Na}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)+{\mathrm{BaCl}}_2\left(\mathrm{aq}\right)\to {\mathrm{BaSO}}_4\left(\mathrm{s}\right)+2\mathrm{NaCl}\left(\mathrm{aq}\right) \\ (\mathrm{Sodium}\mathrm{sulphate})(\mathrm{Barium}\mathrm{chloride})(\mathrm{Barium}\mathrm{sulphate})(\mathrm{Sodium}\mathrm{chloride}) \end{gathered}$$

Therefore, the precipitate formed in a precipitate reaction is an insoluble compound.
