Fractional distillation is a separation technique used to separate components of mixtures based on their boiling point differences. It is more efficient compared to simple distillation and that’s why it is often used to separate components with closer boiling points (less than 400C). In contrast, simple distillation is typically used when the boiling points of … Read more
