CBSE Class 9 Answered

In CBSE Grade 9 SC text book mentioned 25 degree K is the minimum  difference of boiling point required to apply distilation technique to seperate mixture, but in most of the site it mentioned 25  degree Celcius  , which one is correct?

Expert Answer
For separation of liquid mixtures whose difference in boiling points is more than 25°C, then distillation method is used.
 
And if the difference between soluble liquid mixture is less than 25°C, then the separation is carried out by using fractional distillation method.
