Problem: What is the net ionic equation of the reaction of FeCl2 with NaOH? Express your answer as a chemical equation including phases.
FREE Expert Solution
Write the balanced reaction:
FeCl2(aq) + NaOH(aq) → Fe(OH)2(s) + NaCl(aq) → unbalanced
▪ Cl-, Br-, and I- are soluble except when paired with Ag+, Pb2+, Cu+, Hg22+
▪ Hydroxides (OH-) are insoluble except when with Group 1A ions (Li+, Na+, K+, etc.) and ammonium ion (NH4+) and Ca2+, Sr2+, Ba2+
Balancing the reaction equation:
Balance Cl:
FeCl2(aq) + NaOH(aq) → Fe(OH)2 + 2 NaCl(aq)
Balance Na:
FeCl2(aq) + 2 NaOH(aq) → Fe(OH)2 + 2 NaCl(aq)
*everything else is balanced
Balanced reaction equation: FeCl2(aq) + 2 NaOH(aq) → Fe(OH)2 + 2 NaCl(aq)
Before writing the net ionic equation we need to write the total ionic equation first:
