WebJan 5, 2012 · Consider a binary mixture of ethanol and water. Expressions for the excess enthalpy (in J/mol) and heat capacity (in J/mol·K) have been determined for this binary liquid system for the temperature range 298.15 K to 383.15 K by fitting experimental data to an empirical equation [1]. This equation for the excess enthalpy is where is the … WebWater with 1% (volume) acetic acid added was used as the good solvent. Ethanol, an organic solvent, was the poor solvent. Different proportion of ethanol volume mixed with water solution was acted as poor solvents which could provide solubility of regular difference, respectively. Ubbelohde viscometer was used as the viscosity measuring instrument.
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 ...
