🥽

Safety First: Wear virtual safety goggles & lab coat. Keep exhaust ventilation ON.

🧪 1. HCl Titration with Na₂CO₃

Burette, conical flask, indicator color changes & pH titration curves.

Grades 7–12 · Cambridge Chem

⚗️ 2. Metal + Acid Gas Reaction

React Mg, Zn, Fe with HCl. Collect H₂ gas in syringe & squeaky pop test!

Grades 6–10 · Rates of Reaction

🔥 3. Thermal Decomposition

Heat Copper Carbonate with Bunsen burner & bubble CO₂ into limewater.

Grades 7–11 · Chemical Change

💧 4. Precipitates & Equations

Mix aqueous salts, observe colorful insoluble precipitates & filtration.

Grades 8–12 · Salt Preparation

🧫 5. Group 1 Metals + Water

Lithium, Sodium & Potassium on water — reactivity trend down Group 1.

Grade 8 · Reactivity Series

🧾 6. Chromatography of Dyes

Separate dye mixtures on paper & identify components by Rf values.

Grade 9 · Separating Mixtures

⚛️ 7. Atoms & Covalent Bonds

Bohr shells → shared electron pairs in H₂O, CH₄, O₂, N₂, CO₂.

Grade 9 · Atomic Structure & Bonding

🌡️ 8. Exo & Endothermic

Track ΔT: neutralisation heats, ammonium nitrate cools.

Grade 10 · Energy Changes

🔥 9. Burning Magnesium

Dazzling white oxidation → MgO ash → litmus test.

Grade 10 · Oxidation

🔄 10. Metal Displacement

Zn in CuSO₄ — build the reactivity series Mg > Zn > Fe > Cu > Ag.

Grade 10 · Reactivity

🧪 11. Redox Titration (KMnO₄)

Add KMnO₄ until the pink stays — self-indicating endpoint.

Grade 10 · Redox

💡 12. Conductivity of Liquids

Ions or no ions? Bulb + ammeter decide.

Grade 10 · Electrochemistry

⚡ 13. Electrolysis of NaCl

Brine → H₂ + Cl₂ + NaOH (the chlor-alkali process).

Grade 10 · Electrolysis

🏭 14. Copper Electroplating

Plate an iron nail — current × time controls thickness.

Grade 10 · Applications

⚖️ 15. Standard Solution of Na₂CO₃

Weigh 5.30 g → dissolve → make up to the 250 cm³ mark.

Grade 11 · Quantitative

♻️ 16. Equilibrium & Le Chatelier

2NO₂ ⇌ N₂O₄ — shift it with temperature & pressure.

Grade 11 · Equilibrium

📊 17. Period 3 Properties

Na → Cl: structures, melting points & oxide types compared.

Grade 12 · Periodicity

⏱️ 18. Hydrolysis of Halogenoalkanes

AgCl white, AgBr cream, AgI yellow — weakest bond hydrolyses fastest.

Grade 12 · Kinetics

🧡 19. Oxidation of Alcohols

Orange → green? distil vs reflux vs tertiary no-reaction.

Grade 12 · Organic

🍍 20. Esterification

Acid + alcohol → sweet-smelling esters (pineapple, pear, rum).

Grade 12 · Organic

🟡 21. Iodoform Test

Alkaline iodine — yellow CHI₃ with the antiseptic smell.

Grade 12 · Analysis
