If you have some ice floating in water, you have a solid phase present and a . You don't usually talk about "ethanol gas", although you would say "ethanol vapour". To make the liquid water freeze again at this higher pressure, you will have
They won't separate but depending on how much alcohol you use the freezing point will be substantially lowered. In other words it's possible the
2. prepare a water solution of ethyl alcohol and measure the freezing point of the solution. Use the data to estimate the freezing point depression constant for
In today's experiment, you will first determine the freezing point of the t-butyl alcohol by cooling it in cold water. You will then add a solute to the alcohol and
70% water with 30% methanol. The methanol prevents freezing. Some run 50/50 as a maximum but I find 70/30 works much better. More than 50% alcohol or
