Question

In a micro scale distillation, the rate of distillation should be about

a) 1-2 drops per second
b) 10-20 drops per second
c) 100-200 drops per second
d) 1000-2000 drops per second

Answer 1

In micro scale distillation, the recommended distillation rate is 1-2 drops per second to ensure proper separation and safe laboratory practice.

Step-by-step explanation:

In micro scale distillation, the ideal rate of distillation is to maintain a rate that allows for efficient separation without overloading the condenser or causing bumping. The correct rate of distillation for a micro scale setup is approximately 1-2 drops per second. This slow rate ensures that the vapor has enough time to condense properly and that the distillate can be collected without causing the distilled fractions to mix.

Using the distillation rate too high such as 10-20 drops per second, 100-200 drops per second, or 1000-2000 drops per second might lead to poor separation of compounds, loss of materials, and potential safety hazards in a lab setting.
