predict the precipitate that forms when aqueous solutions of silver nitrate and potassium chloride react to form products in a double-replacement reaction. Include a discussion of how to write complete chemical equation describing this reaction.

Question

Silver: $\sf Ag^{+}$  ,  Nitrate: $\sf NO_3^-$

Silver Nitrate: $\sf AgNO_3$ Solubility rules state that Nitrates are soluble with everything, thus $\sf AgNO_3 (aq)$

Potassium: $\sf K^+$  ,  Chloride: $\sf Cl^-$

Potassium Chloride: $\sf KCl$ Solubility Rules state that G1A metals do not have any exceptions, therefore $\sf KCl (aq)$

Double replacement: $\sf AB + CD \to AD + BC$
$$\sf AgNO_3(aq) + KCl(aq) \to ~? ~~+~~~?$$

Once you have finished writing out the rest of your chemical equation, analyze the compounds and interpret whether the compounds are soluble with water. If they are not, you will find a precipitate.
