Your question :
How will you separate a mixture containing petrol and kerosene ( difference in their boiling point is more than 25 degree c) which are miscible with each other?
Answer :
As the difference in boiling points of kerosene and petrol is more than 25 degree Celsius , they can be separated by simple distillation . Petrol with lower boiling point will distil out First living the kerosene with higher boiling point behind .
If the difference between them will be less than 25° C then we will use fractional distillation .
