WebJul 14, 2024 · fecl2 + 2naoh = fe(oh)2(s) + 2nacl Initial amounts of the reactants are given, so, we need to determine which of the reactants is the limiting reactant and use this amount to determine what is asked. However, what is being asked is how many of the FeCl2 is used in the reaction, showing that it is NaOH that is the limiting reactants. WebBalanced reaction of FeCl 2 and NaOH with physical states FeCl 3 (aq) + 3NaOH (aq) = Fe (OH) 3 (s) + 3NaCl (aq) FeCl 3 is soluble in water. Therefore, it exists as an aqueous solution and NaOH also exists as a solution. But, solubility of Fe (OH) 3 is poor in water. Hence it deposits as a precipitate at the bottom of the reaction.
