Answer:

Insoluble salts can be produced by precipitation reactions, in which two aqueous solutions react to produce a precipitate (an insoluble salt).

Explanation:

Examples:

#"NaCl(aq)"+"AgNO"_3"(aq)"##rarr##"AgCl(s)"+"NaNO"_3("aq")"#

#"2KOH(aq)"+"MgSO"_4"(aq)"##rarr##"Mg(OH)"_2("s")"+K"_2"SO"_4"(aq)"#

You can determine which compounds are insoluble by using a chart of solubility rules, such as the one below.
