Finally, we will separate all soluble ionic compounds. We need only consider those
compounds not already separated or that do not have a dash beneath the formula.

We can now write the complete or total ionic equation for each of the reactions.
All we need to do for this step is to write the separated ions and non-ionized
species on one line:
Cr(OH) 3(s) 3 H 3 ClO 4 l Cr 3 3 ClO4 3 H2O
3 K 3 Cl 3 NH 4 PO4 3 l 3 K PO4 3 3 NH4 3 Cl
2 Na CO 3 2 2 H 2 Cl l 2 Na 2 Cl CO2 H 2O
Mg 2 2 NO 3 Ca 2 2 OH l Mg(OH)2 Ca 2 2 NO 3
2 H 2 NO 3 Ba 2 2 OH l Ba 2 2 NO3 2 H2O
2 Li 2 F 2 H SO 4 2 l 2 Li SO4 2 2 HF
