Laboratory Date Name TA Experiment 2- Post- lab Questions I. Chloroform and cyclohexane are organic liquids that are insoluble in water (see Table 2.2), and this causes two distinct liquid phases, an organic phase and a water phase, to form when these organic liquids are mixed with water. However, in a chloroform/water mixture, the water phase is on the top and the organic chloroform phase is on the top, whereas in a cyclohexane/water mixture, the water phase is on the...

oragnic chemistry lab
What extra chemical process, accomplished either via enzymes of chemical methods, must occur before the sugars in corn, potatoes, or grass can be fermented by yeast? What is happening during the fermentation process? Describe the set-up in the lab for the fermentation process. What is the difference in boiling point between water and ethanol? How does this affect the choice of distillation (simple versus fractional)...

Pt.1 predict whether soluble or insoluble.
Pt 2. Miscible or immiscible
Pt 3 and beyond- answering questions
1. For each of the following pairs of solute and solvent, predict whether the solute would be soluble or insoluble. After making your predictions, you can check your answers by looking up the compounds in The Merck Index or the CRC Handbook of Chemistry and Physics. Generally, The Merck Index is the easier reference book to use. If the substance has a solubility...
