Does water and ethanol form a solution
WebThe vast majority of energy needed to boil water comes right before it's at the boiling point. It takes way less energy to heat water to 90ºC than to 100ºC, so the relative amounts of energy required to boil ethanol vs. water are actually as large as stated in the video. It's not really intuitive, but it's one of the odd things about water ... WebSep 17, 2016 · The reaction of methanol and ethanol are based on their p K a values in the reaction. Fist consider the reaction of methanol with water along with their p K a values. C H X 3 O H p K a = 15.5 + N a O H → C H X 3 O X − N a X + + H X 2 O p K a = 15.74. Now you can see that p K a value of water is a bit higher than that of methanol so the ...
