Note the two boundaries for pure water (left) and pure nicotine (right) and mole fractions of nicotine across the horizontal axis. The letter "P" means phases, and this diagram has two regions: single-phase (one liquid, fully dissolved solid), and the other two-phase (two liquids) Here, the curve...

Consider the phase diagram below for a mixture of chloroform and methanol, looking at how the boiling point changes with composition at constant pressure. If you started with a solution that was Xchloroform = 0.1 at a temperature of 333 K, is it possible to use fractional distillation to purify this solution to nearly 100% chloroform? Approximately what concentration (in mole fraction) would you expect you could achieve through fractional distillation? Curves calculated by mod. UNIFAC (Dortmund) Temperature Minimum Azeotrope...
The solid/liquid phase transition of water near 1 atm external pressure is an important feature of our daily lives. Some relevant data concerning the transition include the density of liquid water at 273.15 K (0.999 g cm-3), the density of ice at 273.15 K (0.917 g cm-3), and the enthalpy of fusion of water at 273.15 K (6.008 kJ mol-1). (a) On a phase diagram, this transition appears as a line. Calculate the slope of this transition line near the...

Provide a stoichiometry table for the reaction being performed
in this lab.
PROCEDURE Preparation oft-Pentyl Chloride In a 125-mL separatory funnel, place 10.0 mL of tert-pentyl alcohol (2-methyl-2- butanol, MW = 88.2, d = 0.805 g/mL) and 25 mL of concentrated hydrochloric acid (d 1.18 g/mL). Do not stopper the funnel. Gently swirl the mixture in the separa- tory funnel for about 1 minute. After this period of swirling, stopper the separatory funnel and carefully...
