Write down the possible molecular and ionic equations for the reactions between solutions: a) sodium carbonate and barium copper sulfate; b) potassium sulfite and hydrochloric acid; c) potassium phosphate and aluminum chloride; d) tin and magnesium sulfate.

A) sodium carbonate and barium sulfate do not react, because barium sulfate is insoluble in water.
Na2CO3 + CuSO4 = Na2SO4 + CuO + CO2 – molecular equation
2Na + + CO32- + Cu2 + + SO42- = 2Na + + SO42- + CuO + CO2 – complete ionic equation
CO32- + Cu2 + = CuO + CO2 – abbreviated ionic equation
B) K2SO3 + 2HCl = 2KCl + H2O + SO2 – molecular equation
2K + + SO32- + 2H + + 2Cl- = 2K + + 2Cl- + H2O + SO2 – complete ionic equation
SO32- + 2H + = H2O + SO2 – abbreviated ionic equation
C) K3PO4 + AlCl3 = AlPO4 + 3KCl – molecular equation
3K + + PO43- + Al3 + + 3Cl- = AlPO4 + 3K + + 3Cl- – complete ionic equation
PO43- + Al3 + = AlPO4 – abbreviated ionic equation
D) Sn + MgSO4 – do not react, because Sn has less reducing ability than magnesium.
