Balanced Equation:

Answer 1

Iron(III) chloride and ammonium hydroxide react in a precipitation reaction to form iron(III) hydroxide precipitate and aqueous ammonium chloride. The balanced equation is FeCl₃ (aq) + 3NH₄OH (aq) → Fe(OH)₃ (s) + 3NH₄Cl (aq). Observations include the formation of a brownish-orange precipitate.

Step-by-step explanation:

When aqueous iron(III) chloride is mixed with aqueous ammonium hydroxide, a precipitation reaction occurs. In this reaction, a solid precipitate of iron(III) hydroxide, Fe(OH)3, is formed. The balanced chemical equation for this reaction is:

FeCl3 (aq) + 3NH4OH (aq) → Fe(OH)3 (s) + 3NH4Cl (aq)

Observations for such a reaction would typically include the formation of a brownish-orange solid precipitate which is the iron(III) hydroxide. The products include the insoluble Fe(OH)3 solid and aqueous ammonium chloride, NH4Cl.
