The process of Distillation is able to concentrate ethanol because: a. the boiling point of ethanol (78oC) is lower than the boiling point of water (100oC) b. CO2 is a gas that occupies ~22 liters per mole whereas ethanol is a liquid dissolved in water c. adding egg white traps CO2 bubbles which allows them to be separated from alcohol d. Sodium Aluminum Phosphate binds ethanol and concentrates it e. distillation removes the reducing equivalents “H2” from ethanol and lowers the calorie content making “light” calorie beverages
