Know these three conditions for going to completion.

1. To predict the formation of an insoluble precipitate, you should have
   some knowledge of the solubilities of compounds. Table 9 gives some
   general solubility rules.

TIP

Know the general solubility rules.

Table 9. Solubilities of Compounds

(A table of solubilities could also be used as reference.)

An example of this type of reaction is given in its complete ionic

form.

(K+ + Cl−) + (Ag+ + NO 3 −) → AgCl (s) + (K+ + NO 3 −)

TIP

Notice that the ions “switch” partners.
