Burette Reading Mistake That Costs Marks Some students take the burette reading and then minus 50 from it… But the burette NEVER started at 50. This is one of the most common mistakes I see in titration. The burette shows the volume delivered, not how much is left. So if your initial reading is 0.20 cm³ and final is 22.50 cm³ The volume used is simply: 22.50 – 0.20 = 22.30 cm³ No need to minus 50! 🧪 Accuracy begins with understanding the instrument Let us not subtract what was never there in the first place #stalfordlearningcentre #tuition #singapore #tuitionsg #lab #sciencepractical #olevel #alevel @Selena See
