For example if we synthesized a known liquid that boiled at 120-122 C this value could be used to confirm that we prepared what we were interested in and that our substance was reasonably pure. Boiling point is the temperature at which the saturated vapor pressure equals the external pressure. High molecular or high boiling compounds. Consider for example ethanol consisting of a weight concentration of approximately ninety-five per cent and four per cent of water.
