Question

Write the equation when Sodium hydroxide is added to a solution of Ferric chloride.

Answer 1

Part-1 Sodium hydroxide is added to Ferric chloride.

• The reaction between Sodium hydroxide and Ferric chloride(FeCl₃) is an example of a precipitated reaction.
• When Sodium hydroxide and Ferric chloride (FeCl₃) react, a reddish-brown precipitate form
• The end product of this reaction is Sodium chloride (NaCl) salt and Ferric hydroxide (Fe(OH)₃ which is precipitate.

Part-2 Balanced reaction between Sodium hydroxide and Ferric chloride.

$$\begin{gathered} {\mathrm{FeCl}}_3\left(\mathrm{s}\right)+3\mathrm{NaOH}\left(\mathrm{aq}\right)\to \mathrm{Fe}{\left(\mathrm{OH}\right)}_3\left(\mathrm{s}\right)+3\mathrm{NaCl}\left(\mathrm{aq}\right) \\ \left(\mathrm{Ferric}\mathrm{chloride}\right)\left(\mathrm{Sodium}\mathrm{hydroxide}\right)\left(\mathrm{Ferric}\mathrm{hydroxide}\right)\left(\mathrm{Sodium}\mathrm{chloride}\right) \\ \left(\mathrm{Yellow}\right)\left(\mathrm{Colorless}\right)\left(\mathrm{reddish}\mathrm{brown}\mathrm{ppt}\right)\left(\mathrm{colorless}\right) \end{gathered}$$

Final answer - When sodium hydroxide reacts with ferric chloride. $$\begin{gathered} {\mathrm{FeCl}}_3\left(\mathrm{s}\right)+3\mathrm{NaOH}\left(\mathrm{aq}\right)\to \mathrm{Fe}{\left(\mathrm{OH}\right)}_3\left(\mathrm{s}\right)+3\mathrm{NaCl}\left(\mathrm{aq}\right) \\ \left(\mathrm{Ferric}\mathrm{chloride}\right)\left(\mathrm{Sodium}\mathrm{hydroxide}\right)\left(\mathrm{Ferric}\mathrm{hydroxide}\right)\left(\mathrm{Sodium}\mathrm{chloride}\right) \\ \left(\mathrm{Yellow}\right)\left(\mathrm{Colorless}\right)\left(\mathrm{reddish}\mathrm{brown}\mathrm{ppt}\right)\left(\mathrm{colorless}\right) \end{gathered}$$
