- B. Burette
- C. Conical flask
- D. Test tube
Answer
Distillation flask
Explanation
The correct option is Distillation flask. Distillation flask is the best answer because it directly supports the AQA A-Level Chemistry objective to required practical 5: distil a product from a reaction. This reasoning is anchored to A-level required practical activities in A-level practical endorsement and required practical activities, and it separates required practical from similar A-Level ideas rather than relying on a vague recall statement. Other options are weaker if they use the wrong evidence, calculation, mechanism, observation, unit, or conclusion for this subtopic.
Common mistake
Common Mistake in Distillation
Students often forget to account for the loss of product during the distillation process, leading to inaccurate yield calculations.
To fix this, remember to measure the actual volume of distillate collected and compare it to the theoretical yield. Use the formula for percentage yield: Percentage Yield = (Actual Yield / Theoretical Yield) x 100 Substituting values: If the actual yield is 30 g and the theoretical yield is 50 g, then: Percentage Yield = (30 g / 50 g) x 100 = 60% Final answer: The percentage yield of the distillation is 60%. Keep the correction anchored to A-level required practical activities and the objective: Required practical 5: distil a product from a reaction.
