Boiling point of water ethanol mixture
WebFor example, the boiling point of ethanol is approximately 78 degrees Celsius. While the boiling point of water is 100 degrees Celsius. And so a mixture of ethanol and water is going to have a boiling point someplace in between. And so you could imagine we can keep heating up this solution. We're going to go beyond the boiling point of ethanol ... WebThe boiling point of this mixture is 78.2°C, compared with the boiling point of pure ethanol at 78.5°C, and water at 100°C. You might think that this 0.3°C doesn't matter much, but it has huge implications for the …
