Magnesium sulfate (MgSO4) has a solubility of 38.9 g/ 100 g H2O at 30C. A solution is prepared by adding 9.50 g of MgSO4 to 25.0 g of water at 40C. A homogeneous mixture is obtained. Is the solution saturated, unsaturated, or supersaturated? One gram of magnesium sulfate is added to the solution cooled to 30C. Would you expect some of the MgSO4 to precipitate? If so, how much? If not, how much more MgSO4 can be added before precipitation takes place?

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
