Question

is it possible to find out adulteration of kerosene in petrol with evaporation technique?

Answer 1

yes while petrol vaporises first then we can separate each

Answer 2

Hey Kshitija,

● Answer -
Yes, off course. Adulteration of kerosene in petrol can be detected by evaporation (particularly fractional distillation).

● Explanation -
- Petrol & kerosene evaporate at different temperatures and therefore can be separated by fractional distillation.
- Petrol sample is heated with gradually increasing thr temperature.
- Petrol boils at 150℃, thus will evaporate first & can be collected.
- Kerosene will boil at 200℃, thus can br collected later.
- This is how presence of kerosene in petrol sample can be detected.

Thanks for asking..
