Sodium Hydroxide and Iron(III) Chloride (Rust Color)

3NaOH + FeCl3 → Fe(OH)3 + 3NaCl

概述

When sodium hydroxide is added to iron(III) chloride solution, a characteristic rust-brown precipitate of iron(III) hydroxide forms. This gelatinous precipitate is used to identify iron(III) ions in qualitative analysis.
