Question

Which product in the reaction forms a precipitate? KNO3 AgCl AgK no precipitate formed.

Answer 1

The precipitate formed in the reaction has been AgCl. Hence, option B is correct.

The precipitate has been the solid insoluble substance that has been formed as the product in the double displacement reaction.

The precipitate settles down in the aqueous reaction mixture and are resulted from the double displacement reaction.

Which one  is the precipitate?

The reaction of silver nitrate and KCl has been:

$\rm AgNO_3\;+\;KCl\;\rightarrow\;AgCl\;+\;KNO_3$

The reactants in the reaction are in the aqueous form. Thus, silver nitrate and KCl are aqueous.

The potassium nitrate has been an aqueous solution, while the silver chloride has been the solid product that precipitates out.

$\rm AgNO_3\;(aq)\;+\;KCl\;(aq)\rightarrow\;AgCl\;(\downarrow)+\;KNO_3\;(aq)$

Thus, the precipitate formed in the reaction has been AgCl. Hence, option B is correct.
