This experiment aims to detect the ferric ion (Fe³⁺) in an iron chloride solution. When bases such as ammonium hydroxide or sodium hydroxide are added to the iron chloride solution, a reddish-brown precipitate of ferric hydroxide is formed. When hydrochloric acid is added, this precipitate dissolves......
