Answer
For the following answers, the balanced formula equation is first, followed by the complete ionic equation, then the net ionic equation.
a. No reaction occurs since all possible products are soluble salts.
b. 2 Al(NO3)3(aq) + 3 Ba(OH)2(aq) → 2 Al(OH)3(s) + 3 Ba(NO3)2(aq)
2 Al3+(aq) + 6 NO3(aq) + 3 Ba2+(aq) + 6 OH−(aq) →2 Al(OH)3(s) + 3 Ba2+(aq) + 6 NO3(aq)
Al3+(aq) + 3 OH(aq) → Al(OH)3(s)
c. CaCl2(aq) + Na2SO4(aq) → CaSO4(s) + 2 NaCl(aq)
Ca2+(aq) + 2 Cl(aq) + 2 Na+(aq) + SO42-(aq) → CaSO4(s) + 2 Na+(aq) + 2 Cl−(aq)
Ca2+(aq) + SO42−(aq) → CaSO4(s)
d. K2S(aq) + Ni(NO3)2(aq) → 2 KNO3(aq) + NiS(s)
2 K+(aq) + S2−(aq) + Ni2+(aq) + 2 NO3(aq) → 2 K+(aq) + 2 NO3(aq) + NiS(s)
Ni2+(aq) + S2-(aq) → NiS(s)
