During lab, students mixed two solutions of soluble ions in a ceramic well to determine if a precipitate forms. Write the dissolution reaction for the ionic solids below. (Use the lowest possible coefficients. Include states-of-matter under the given conditions in your answer.) a. Ca(NO3)2
b. Na3PO4

a.

b.

Explanation:

Hello,

In this case, considering that the dissolution reaction of a solid in aqueous solutions involve the dissociation (separation) of both its cation and anion for the required salts we write:

a.

b.

Thus, a two is required for nitrate anions in a. in order to balance it at the reactant and a three is required for sodium cations in b. in order to balance it as well.

Best regards.
