Practical 3 | Determining the Boiling Point of Ethanol | Matric Chemistry Punjab Board

Is video me hum dekhenge ke kaise ethyl alcohol (ethanol) ka boiling point determine kiya jata hai. Ye Matric Chemistry ka important practical hai jo Punjab Board (BISE Lahore, Multan, Faisalabad, Gujranwala aur doosre Punjab boards) ke students ke liye hai. 🔬 Apparatus: ✅ Ethyl alcohol (Ethanol) sample ✅ Capillary tube ✅ Thermometer ✅ Fusion tube (or test tube) ✅ Beaker (water bath) ✅ Wire gauze ✅ Tripod stand ✅ Burner or heating source ✅ Pipette or dropper ✅ Clamp stand 🧪 Procedure (Student-friendly): ✅ Take ethanol in the fusion tube and insert the capillary tube inverted. ✅ Attach the fusion tube to a thermometer and place it in a water bath. ✅ Heat the water bath slowly using a burner. ✅ Observe the capillary tube carefully; note when bubbles continuously emerge. ✅ Stop heating and record the temperature when bubbling stops and liquid rises in the capillary. ✅ This recorded temperature is the boiling point of ethanol. 📌 Expected Result: Pure ethanol has a boiling point of approximately 78°C. 📚 Importance: 🔹 Helps understand the concept of boiling point determination 🔹 Teaches correct setup and safe heating techniques in chemistry labs 🔹 Useful for Punjab Board Matric practical exams and viva preparation Ye experiment Matric Punjab Board Chemistry Practical Series ka hissa hai aur students ke liye bohot useful hai school labs aur exam preparation me.
