What is the effect of a non-volatile impurity on the boiling point of a substance? of a volatile impurity? A non volatile impurity which is added to the volatile liquid‚ it’s boiling point will increase. It is due to some of effective surface area which is available for evoperation is occupied by non volatile substance. If another volatile impurity is added then 1) if it does not chemically react with given liquid then boiling point will decreade due to increase in vapour pressure. 2) if it chemically

A prominent Anglo-indian‚ Derozio played a major role in introducing western attitudes into Indian intellectual life. He taught literature and history at Hindu College‚ Calcutta and was perhaps the first nationalist poet of modern India. Drawing inspiration from French Revolution‚ he inspired his pupils to think freely and rationally‚ question all authority‚ oppose meaningless customs and traditions. He started a discussion group—the Academic Association—to enable interaction amongst students. He
