Question

Predict the precipitate that forms when aqueous solutions of silver nitrate and potassium chloride react to form products in a double-replacement reaction.

Answer 1

You would expect to see a white precipitate

Answer 2

Answer: The solid precipitate formed in the above reaction is silver chloride.

Step-by-step explanation:

Precipitation reaction is defined as the reaction in which an insoluble salt is formed when two solutions are mixed containing soluble substances. The insoluble salt settles down at the bottom of the reaction mixture.

Double displacement reaction is defined as the reaction in which exchange of ions takes place.

`AB+CD\rightarrow CB+AD`

The chemical equation for the reaction of silver nitrate and potassium chloride follows:

`AgNO_3(aq.)+KCl(aq.)\rightarrow AgCl(s)+KNO_3(aq.)`

By Stoichiometry of the reaction:

1 mole of aqueous solution of silver nitrate reacts with 1 mole of aqueous solution of potassium chloride to produce 1 mole of solid silver chloride and 1 mole of aqueous solution of potassium nitrate

Hence, the solid precipitate formed in the above reaction is silver chloride.
