AP Chem solubility and precipitation

Question

Write a balanced equation, with state symbols, to show the dissociation of each of the following ionic solids when they are dissolved in water.

a. __K2S (s) -->

b. __Ni(NO3)2 (s) -->

c. __Na3PO4 (s) -->

d. __(NH4)2CO3 (s) -->

J.R. S. · Accepted Answer

K2S(s) ==> 2K+(aq) + S2-(aq)Ni(NO3)2(s) ==> Ni2+(aq) + 2NO3-(aq)Na3PO4(s) ==> 3Na+(aq) + PO43-(aq)(NH4)2CO3(s) ==> 2NH4+(aq) + CO32-(aq)
