10. Course overview: - Introduction to the theory and applications of analytical chemistry.

Laboratory emphasis on obtaining and interpreting quantitative data. Statistical data analysis, equilibrium expressions, pH, volumetric and gravimetric analysis, fundamentals of spectroscopy, fundamentals of electrochemistry, and analytical separations. The material presented in this course book will enable the students to obtain knowledge of Qualitative and Quantitative Analysis methods. Several experiments have been used to support this approach in the laboratory class.

- Analytical chemistry is the study of the separation, identification, and quantification of the chemical components of natural and artificial materials. Analytical Chemistry is the basic for other fields of Chemistry. Descriptive chemistry, elements and compounds; basic chemical calculations, mole problems, stoichiometry, and solution concentrations; gas laws; thermochemistry; quantum theory and electronic structure of atoms; periodic

- properties of the elements; nuclear chemistry; chemical bonding.

15. Student learning outcome:

Expected Learning Outcomes

Upon successful completion of this course, students will therefore:

Be able to use basic concepts in moles and chemical bonding theory by predicting

both the chemical properties (e.g. periodic trends, reactivates) and the electronic.

Be able to interpret experimental data (in both tabular and graphical form) by

appropriately setting up and solving scientific problems using analysis with

proper attention to scientific units and significant figures.



Be able to demonstrate an understanding of the role of energy in physical changes

and chemical reactions by predicting the direction and magnitude of energy

changes and by performing thermochemical calculations.

the laws and molecular theory to processes involving gases.

Demonstrate awareness and appreciation of the relevant applications of chemistry

in society and in everyday life.

0.03 M Ag+ with 25 ml of 0.05 M EDTA that was buffered at pH 3. KAgY = 2.1 x

107

2. True or false type of exams:

What are the differences between Mohr, Fajans and Volhard titrations? b- What

is systematic error and how it is removed?

c- What is the difference between adsorption and absorption? d-



What is galvanic cell, their construction and function?

e- What is the coordination bond and what are the conditions for complex

formation?

f- Describe Standard Hydrogen Electrode and its function.

20. Extra notes:

Analytical chemistry is an important branch of chemistry that involves qualitative

and quantitative analysis.

Qualitative analysis includes identifying the components of a sample. Quantitative

analysis includes determining the amount of the analyte in the sample.

Analyte is a species wanted to determine.

Sample contains the analyte with other components

By qualitative analysis we know the content of the sample and with the quantitative analysis



We can determine the amount of each component (analyte) in the sample. So

usually qualitative analysis is performed before quantitative analysis.

Replicate samples or replicates are portions of a material approximately the

same size that are carried through an analytical procedure at the same time

and in the same way.

Replication improves the quality of the results and provides a measure of

reliability.

Interference or interferent is a species that cause an error in an analysis by

enhancing or attenuating (making smaller) the quantity being measured
