What are the products for the following reaction: #Na_3PO_4 + CaCl_2 -> ?#
The products are soluble sodium chloride,
The products of this reaction can be predicted because this is a double replacement reaction, also called a double displacement, and if a precipitate forms, a metathesis. These reactions can also form an insoluble gas that bubbles out of solution, or water in a neutralization reaction.
The cations in the above reaction are the sodium and calcium ions,
One of the two products is a precipitate because it is insoluble in water. You can determine which is the precipitate by using a list or table of solubility rules, such as the one below.
Notice that you first look at the anions, and then the exceptions involving cations. The anions in the products are
The other anion is
