Tutorial example

This salt will be acidic by partial hydrolysis (salt of a weak base and a strong acid). The pH of the salt solution is given by equation (1.2). 

If 1 M HCl is reacted with 1 M ephedrine, the resulting concentration of ephedrine hydrochloride will be 0.5 M therefore, 

2 Calculate the pH of 0.05 m sodium acetate, given that the pKa of acetic acid is 4.66. 

2 Since sodium acetate is the salt of a strong base and a weak acid, it will be basic by partial hydrolysis. We can therefore use equation (1.3) for weak bases to calculate the answer. 

3 Calculate the concentration of acetic acid to be added to a 0.1 M solution of sodium acetate to give a buffer of pH 5 (pKa of acetic acid = 4.66).

Extraframework cations are needed in anionic zeolites for charge balance, and for several zeolite topologies their locations are well investigated [281, 282]. Different cations have been investigated by solid state NMR in the past with different NMR properties and different project targets. We restrict this section to a tutorial example on sodium cation motion in sodalite and cancrinite structures [283-285], 23Na has a nuclear electric quadrupole moment, and quadrupolar interaction is useful to investigate jump processes, especially when they are well defined. 

A second tutorial example may be useful. Suppose that an extended communication network, modeled as a large two-dimensional square-lattice grid connected to heavy bars at two opposite boundaries, is attacked by a stochastic saboteur, who, with wire-cutters, severs the grid interconnections. What fraction of the links must be cut in order to isolate the two bars from each other The answer, given by a a percolation... 

It is straightforward to show that the special case of a spin having an axially synunetric g tensor (widely used as a tutorial example for the theory behind ESR spectroscopy ), when direct use is made of Eqs. (2.18) and (2.18 )> leads to a continued fraction of the same kind as Eq. (2.19) with the expansion parameters...

A worked example of the use of NMR and other techniques of structure elucidation is presented as Tutorial example Q4 at the end of the chapter. This example should be studied closely to appreciate the strategies employed to solve unknown chemical structures. 

The following section presents a step-by-step tutorial example of the implementation of a PBPK model for chloroform. The model has been coded in Matlab Version 7.0, and effort is made to design it in the form of a reference implementation that is easily extensible for PBPK models for other chemicals. A summary of the Matlab code is provided in Table 43.4, and code listings are presented in the appendix. 

This section addresses the application of a dynamic optimization-based design approach to RD. The liquid-phase esterification reaction of C4 and methanol in the presence of inert nC4 in a staged RD column is used as tutorial example. Similar to the study on binary distillation (Bansal et al., 2000 Bansal, 2000) and on the synthesis of ethyl acetate by RD (Georgiadis et al, 2002), both spatial-related e.g. column diameter and heat exchanger areas) and control-related e.g. gain, set-point and reset time) design variables are optimized with respect to economic and dynamic performance in the presence of time-varying disturbances. 

The preceding generalizations concerning information content from various types of EPR experiments can be made more concrete by considering the series of spectra for Cu(dtc)2 shown in Figures 1-5. The spectra for this complex are better resolved than for most transition metal complexes, which makes them well suited to be a tutorial example.

Start-up kit consists of laboratory materials, as well as other required materials for successfully performing the exercise, such as source codes, scripts, and binary files, collected as separate archive files (e.g. tar, zip, or 7z), usually one archive per exercise, and sometimes an additional one archive for a course. In addition to laboratory exercise materials, some authors give a larger number of various supporting materials that can help the students, and make the process of conducting the exercise more effective. The materials are classified in terms of their purpose (lab instructions, work materials for students, exercise solution, tutorial documents, and tutorial examples) and scope of use (exercise, course).
