Chapter 26: Q6P (page 746)

Propose a scheme for separating trimethylamine, dimethylamine, methylamine, and ammonia from one another by ion-exchange chromatography.

Short Answer

Expert verified

Principle of ion-exchange chromatography:Molecules are separated because of difference in their charges and are eluted with a solution which has a varying ionic strength. When that kind of solution passes through the column the molecules are highly separated according to their different charges.

Step by step solution

01

Order of separation of molecules

Molecules will be separated in the following order:

Ammonia < trimethylamine < methylamine < dimethylamine due topKa their values.

The exchange capacity of an ion-exchange resin can be defined as the number of moles of charged sites per gram of dry resin. Describe how you would measure the exchange capacity of an anion-exchange resin by using standard NaOH, standard HCl, or any other reagent you wish.

Material balance. If you intend to measure all the anions and cations in an unknown, one sanity check on your results is that the total positive charge should equal the total negative charge. The table lists concentrations of anions and cations measured in pond water in an undergraduate experiment and expressed in mg/mL.

Find the total concentration of negative and positive charge (mol/L) to assess the quality of the analysis. What do you conclude about this analysis?

When the following three compounds are separated by micellar electrokinetic chromatography at, three peaks are observed. When 10mMvฮฑ-cyclodextrinis added to the run buffer, two of the three peaks split into two peaks, giving a total of five peaks. Explain this observation and predict which compound does not split.

Electrophoretic mobility of the anionic form A2 of the weak acid phenol (HA=C6H5OH)and its derivatives are:

(a) Explain the trend in electrophoretic mobility from phenol to 4-methylphenol to 4-ethylphenol.

(b) Predict the electrophoretic mobility of the analytes at pH 10.0. Explain why the predicted mobility differs from mA2. (c) The electroosmotic mobility is toward the cathode and greater in magnitude than the analyte electrophoretic mobilities. In what order will the peaks appear in the electropherogram at pH 10.0?
