The equations that show a precipitation reaction would be [tex]MgSO_4(aq) + CaCl_2(aq) --- > MgCl_2(aq) + CaSO_4(s)[/tex], [tex]FeCl_2(aq) + Na_2CO_3(aq) --- > FeCO_3(s) + 2NaCl(aq)[/tex], and [tex]2AgNO_3(aq) + Na_2S(aq) --- > Ag_2S(s) + 2NaNO_3(aq)[/tex]

What is a precipitation reaction?

It is a reaction in which two soluble salts react in aqueous solutions to form one soluble and one insoluble salt.

Thus, all the equations with an insoluble salt as one of the products will qualify as precipitation reactions. The insoluble is designated as (s).

Hence, the following are precipitation reactions:

  • [tex]MgSO_4(aq) + CaCl_2(aq) --- > MgCl_2(aq) + CaSO_4(s)[/tex]
  • [tex]2AgNO_3(aq) + Na_2S(aq) --- > Ag_2S(s) + 2NaNO_3(aq)[/tex]
  • [tex]FeCl_2(aq) + Na_2CO_3(aq) --- > FeCO_3(s) + 2NaCl(aq)[/tex]
