Rusting of Iron Experiment

Rusting of iron is a common chemical process that we see in daily life. This simple experiment helps students understand how iron reacts with air and moisture.

In this article, we will explain the rusting of iron experiment, materials required, steps, and its working principle.

🔩 What is Rusting?

Rusting is a chemical reaction in which iron reacts with oxygen and water to form rust (iron oxide).

👉 Rust is reddish-brown in color.

🧰 Materials Required

Iron nails

Water

Test tubes or small containers

Oil

Calcium chloride (optional)

Corks or lids

Iron Nails Pack

Glass Test Tubes Set

Laboratory Beaker Set

Calcium Chloride

School Chemistry Kit

🔧 Steps to Perform the Experiment

1️⃣ Take three test tubes

2️⃣ Put iron nails in each tube

👉 Tube A: Add water and leave open

👉 Tube B: Add boiled water + oil layer (no oxygen)

👉 Tube C: Add dry air with calcium chloride (no moisture)

3️⃣ Close tubes and leave for 2–3 days

👁️ Observation

Tube A → Rust forms (air + water present)

Tube B → No rust (no oxygen)

Tube C → No rust (no water)

👉 Rusting needs both air and moisture.

💡 Working Principle

Rusting is an oxidation reaction.

Iron reacts with oxygen and water

Forms hydrated iron oxide (rust)

👉 Formula:

Iron + Oxygen + Water → Rust (Fe₂O₃·xH₂O)

⚠️ Safety Tips

Handle glass carefully

Do not spill chemicals

Wash hands after experiment

Keep setup undisturbed
