The Green Blob

In this experiment, we investigate the chemical reactions between iron acetate and ammonium hydroxide. Initially, steel wool is soaked in vinegar, facilitating a reaction that produces iron acetate over five days. The subsequent mixing of iron acetate with ammonium hydroxide results in a new reaction, yielding ammonium acetate and iron hydroxide. This experiment highlights the fascinating transformations in chemical compounds and provides insight into the behavior of acids and bases in chemical interactions.

  1. The Green Blob By: Hayley Monroe Period 6

  2. The Procedure: Part 1 • Fill half of a jar with steel wool • Contains iron (Fe2) • Add enough vinegar to cover the steel wool • Vinegar = acetic acid (C2H4O2) • Let sit for five days

  3. During the Five Days… • Chemical reaction occurs • Iron (from the steel wool) and vinegar (acetic acid) combine to produce iron acetate • Fe2 + C2H4O2 -> Fe(C2H3O2)2

  4. The Procedure: Part 2 • Get another jar • Add equal amounts of iron acetate (Fe(C2H3O2)2) and ammonium hydroxide (NH4OH) • Stir and observe

  5. After Mixing… • Chemical reaction occurs • Ammonium hydroxide and iron acetate combine to produce ammonium acetate and iron hydroxide • NH4OH + Fe(C2H3O2)2 -> C2H3O2NH4 + Fe(OH)2
