We are asked to find the products of the double displacement reaction given:

FeCl3(aq) +  Ba(OH)2(aq) → 

Recall that in a double displacement reaction, the positive ions (cations) and the negative ions (anions) of the two reactants will swap or switch places.


Let us look at the components of the compounds first and get the charges of its ions through oxidation states:

FeCl3(aq)  

  • Oxidation State of Cl = -1, Total charge = 0, Fe = x

Oxidation number of Fe = 1(x) + 3(-1) = 0

Oxidation number of Fe = x - 3 = 0

Oxidation number of Fe = x = +3

Therefore, we have Fe3+ and Cl-


Ba(OH)2(aq) 

  • Oxidation State of OH = -1, Total charge = 0, Ba = x

Oxidation number of Ba = 1(x) + 2(-1) = 0

Oxidation number of Fe = x - 2 = 0

Oxidation number of Fe = x = +2

Therefore, we have Ba2+ and OH-
