Question

What temperature is the reflux carried out at for Lab ?

a) 25°C
b) 100°C
c) Room temperature
d) Variable temperature

Answer 1

In the context of a laboratory reflux, the temperature at which the reflux is carried out typically depends on the boiling point of the solvent used, rather than a set temperature such as 25°C.

Step-by-step explanation:

Room temperature is commonly accepted to be 25°C. When performing a reflux in a laboratory setting, the temperature at which the reflux is carried out can depend on the boiling point of the solvent used. Nonetheless, room temperature, if mentioned, is taken as 25°C.

If one must perform the experiment at room temperature, the substance would not be refluxed since refluxing typically occurs at the boiling point of the solvent. Therefore, without further context on the specific solvent or other conditions, the question cannot be accurately answered. For instance, water boils at 100°C, and ethanol boils around 78°C, so the required reflux temperature would be around these points, respectively, if using these solvents.
