Question
Chapter 1, Problem 1.29NP
Interpretation Introduction
Interpretation: The final volume of the balloon needs to be determined, if a balloon is filled with 11.50 L of Ar at 18.7 °C and 1 atm rises in the atmosphere at pressure 207 torr and temperature -32.4 °C.
Concept Introduction: The ideal gas equation is the equation which gives the relation between P, V, n and T of gases. It can be written as:
Here, P is pressure, V is volume, n is number of moles, R is Universal gas constant and T is temperature.

You have now performed a liquid-liquid extraction protocol in Experiment 4. In doing so, you
manipulated and exploited the acid-base chemistry of one or more of the compounds in your
mixture to facilitate their separation into different phases. The key to understanding how liquid-
liquid extractions work is by knowing which layer a compound is in, and in what protonation state.
The following liquid-liquid extraction is different from the one you performed in Experiment
4, but it uses the same type of logic. Your task is to show how to separate apart Compound
A and Compound B.
. Complete the following flowchart of a liquid-liquid extraction. Handwritten work is
encouraged.
•
Draw by hand (neatly) only the appropriate organic compound(s) in the boxes.
.
Specify the reagent(s)/chemicals (name is fine) and concentration as required in Boxes 4
and 5.
•
Box 7a requires the solvent (name is fine).
•
Box 7b requires one inorganic compound.
