Chapter 23: Q3P (page 629)

If you wish to extract aqueous acetic acid into hexane, is it more effective to adjust the aqueous phase to or ?

Short Answer

Expert verified

When the pH is adjusted to 8, it becomes a basic solution and acetic acid would be in its anionic form.

Step by step solution

01

of 2

Let us determine whether it is more effective to adjust the aqueous phase to pH3orpH8 if we intend to extract aqueous acetic acid into hexane.

02

0f 2

Now, let us adjust the aqueous phase to pH=3

  • The acetic acid has a low localid="1654834546504" pH,and as we said before - similar dissolves in similar
  • When the pH gets adjusted to 8, this would be a basic solution and acetic acid would be in its anionic form.
  • It is to be noted that we didn鈥檛 want an anion, but the acid in its original form.
  • Result :
    When we extract aqueous acetic acid into hexane andpH is adjusted to 8, it becomes a basic solution and acetic acid would be in its anionic form.

A chromatographic procedure separatesof unknown mixture on a column with a length ofand a diameter of. (a) What size column would you use to separateof the same mixture? (b) If the flow ison the small column, what volume flow rate should be used on the large column? (c) The mobile phase occupiesof the column volume. Calculate the linear velocity for the small column and the large column.

In chromatography, resolution is governed by (a) the number of plates, (b) relative retention, and (c) retention factor. Construct a set of graphs to show the dependence of resolution on each of these three parameters. Comment on the nature of the dependence of resolution on each of these three parameters.

An open tubular column is 30.01 mlong and has an inner diameter of 0.530mm. It is coated on the inside wall with a layer of stationary phase that is3.1渭尘thick. Unretained solute passes through in 2.16min, whereas a particular solute has a retention time of 17.32min. (a) Find the linear velocity and volume flow rate. (b) Find the retention factor for the solute and the fraction of time spent in the stationary phase.(c) Find the partition coefficient, K 5 cs/cm, for this solute.

A layer with negligible thickness containing 10.0nmol of methano(D=1.6脳10-9m2/s)was placed in a tube of water 5.00 cm in diameter and allowed to spread by diffusion. Using Equation 23-27, prepare a graph showing the Gaussian concentration profile of the methanol zone after 1.00,10.0, and 100 min. Prepare a second graph showing the same experiment with the enzyme rib nuclease(D=1.12脳10-9m2/s).
