Final answer:
The physical states in the reaction of FeCl₃ with NH₄OH are Fe(OH)₃ as a solid (precipitate) and NH₄Cl as an aqueous solution. Fe(OH)₃ is insoluble and precipitates, while NH₄Cl is soluble.
Step-by-step explanation:
The chemical reaction you're referring to is between iron(III) chloride (FeCl₃) and ammonium hydroxide (NH₄OH). When these react, they form iron(III) hydroxide (Fe(OH)₃) and ammonium chloride (NH₄Cl).
Based on solubility rules, Fe(OH)₃ is insoluble in water and will precipitate as a solid (s), which means it will form a precipitate. The ammonium chloride (NH₄Cl), however, is soluble in water and will exist in the aqueous phase (aq).
The corrected balanced chemical equation, with the physical states, is:
FeCl₃(aq) + 3NH₄OH(aq) → Fe(OH)₃(s) + 3NH₄Cl(aq)
This shows that the Fe(OH)₃ will be in a solid state, while NH₄Cl will be in an aqueous state within the reaction mixture.
