# Problem: From the balanced molecular equations, write the complete ionic and net ionic equations for the following:(a) K2C2O4(aq) + Ba(OH)2(aq) ⟶ 2KOH(aq) + BaC2O4(s)

###### FREE Expert Solution

Step 1: Write the total or full ionic equation.

soluble ionic compounds separate and become ions in the chemical equation
compounds that are aqueous can break up into ions
insoluble compounds (solids, liquids, and gases) will not break up the solution

The given reaction is balanced

K2C2O4(aq) + Ba(OH)2(aq) ⟶ 2 KOH(aq) + BaC2O4(s)

▪ K2C2O4(aq) → 2 K+(aq) + C2O42-(aq)
▪ Ba(OH)2(aq) → Ba2+(aq) + 2 OH-(aq)
▪ 2 KOH(aq) → 2 K+(aq) + 2 OH-(aq)

Complete Ionic Equation:

2 K+(aq) + 2 C2O42-(aq) + Ba2+(aq) + 2 OH-(aq)2 K+(aq) + 2 OH-(aq) + BaC2O4(s)

Step 2: Write the net ionic equation.
