Question

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
chemPadHelp The two solutions, when mixed, will have two cations and two anions. (c) Based on your lab results, enter the cation and anion for which a precipitate will form. (Separate substances in a list with a comma.) chemPadHelp

(d) Write the net precipitation reaction that occurs. (Use the lowest possible coefficients. Include states-of-matter under the given conditions in your answer.) chemPadHelp

Explanation / Answer

Dissolution reactions for the ionic solids,

(a) Ca(NO3)2(aq) ---> Ca2+(aq) + 2NO3-(aq)

(b) Na3PO4(aq) ----> 3Na+(aq) + PO4^3-(aq)

Mixed the two solutions

(c) Cation for the precipitate : Ca2+

Anion for the precipitate : PO4^3-

(d) Net precipitation reaction : 3Ca2+(aq) + 2PO4^3-(aq) ---> Ca3(PO4)2(s)
