You may have noticed an (s) next to one of the products in some double replacement reactions. An (s) next to a compound signifies that it is an insoluble solid, also know as a precipitate. Precipitates can be either cloudy or chunky substances of various colors in an ionic solution. To predict if a product in a double replacement reaction forms a precipitate, you need to use the solubility rules found here.

Answers:
Na2S + Cd(NO3)2 → CdS + 2NaNO3:cadmium sulfide
FeCl3 + 3KOH → 3KCl + Fe(OH)3:iron (III) hydroxide
Na2CO3 + Ba(NO3)2 → BaCO3 + 2NaNO3:barium carbonate
