Question

fecl₃ + naoh → fe(oh)₃ + nacl
the double - replacement reaction shown above is between iron chloride (right) and sodium hydroxide. the products of this reaction are iron (iii) hydroxide and sodium chloride.

Explanation:

Step1: Balance Fe atoms

There is 1 Fe atom on both sides initially.

Step2: Balance Cl atoms

On the left side, there are 3 Cl atoms in \(FeCl_3\). On the right side, Cl is in \(NaCl\). So, put a 3 in front of \(NaCl\). Now the equation is \(FeCl_3+NaOH
ightarrow Fe(OH)_3 + 3NaCl\).

Step3: Balance Na and OH⁻ atoms

On the right side, there are 3 Na atoms (from \(3NaCl\)) and 3 \(OH^{-}\) (from \(Fe(OH)_3\)). So, put a 3 in front of \(NaOH\). The balanced equation is \(FeCl_3 + 3NaOH=Fe(OH)_3+3NaCl\).

Answer:

\(1FeCl_3 + 3NaOH = 1Fe(OH)_3+3NaCl\)
