Qualitative anion

🎶 “Anion Song (Form 4 Chemistry)”

(Verse 1)

When we test for anions,

We know what to do,

Carbonate with acid

Makes bubbles coming through.

The gas turns limewater milky,

That’s how we see—

Carbonate ions are present clearly.

---

(Chorus)

🎵 Carbonate makes bubbles,

Sulfate turns white,

Chloride forms a solid

Shiny, bright.

Nitrate shows a brown ring,

Yes, it’s true—

These are the tests that anions do. 🎵

---

(Verse 2)

Sulfate with barium chloride

Forms white that won’t dissolve.

Add a little acid,

The solid still stays whole.

Chloride with silver nitrate

Makes white that fades away

When ammonium hydroxide

Joins the test today.

---

(Chorus)

🎵 Carbonate makes bubbles,

Sulfate turns white,

Chloride forms a solid

Shiny, bright.

Nitrate shows a brown ring,

Yes, it’s true—

These are the tests that anions do. 🎵

---

(Verse 3)

Nitrate’s brown ring forming

Between the layers two,

FeSO₄ and acid

Make the colour shine through.

Now we’ve learned the anions,

The tests that we must know—

Form 4 chemistry

Ready, set, go!

---

(Final Chorus)

🎵 Carbonate makes bubbles,

Sulfate turns white,

Chloride dissolves in base

Clean and bright.

Nitrate’s brown ring tells us

What is true—

These are the tests that anions do. 🎵
