「成績，不只是在於你知道什麼，而在於你表現什麼。」

成功法則第一招：一定要來上課！

For most its users, analytical chemistry is a tool – not an end in itself.

If you are interested in biology, medicine, environmental science, geology, oceanography, or archeology, you will rely on chemical analyses to answer important questions.

It is possible that you will make measurements yourself, but it is more likely that you will simply be a consumer of analytical results.

What Am I Doing in This Course?

Goals of this course

(1) To understand how analysts derive the results that you will use.

(2) To understand the limitations (the uncertainties) of the results.

(3) To develop laboratory skills and careful work habits that you can apply in your field.

This course will help you, as an informed citizen

To appreciate how quantitative information is obtained and interpreted.

And it should help give you a basis for positive actions in your own field of interest.

General Steps in a Chemical Analysis

1) Formulation the question

2) Selecting analytical procedures

3) Sampling

4) Sample preparation

5) Analysis

6) Reporting & interpretation

7) Drawing conclusions

Naming Simple Compounds IUPAC - I

1. Binary compounds (Type I ; ionic)1) cation + anion (ide)

Left right

2) See p.35 rules & examples : NaCl

3) Table 2.3 sodium chlorine ide

2. Binary compounds (Type II ; ionic)– for metals with more than one type of ion– Table 2.4 -ic / -ous– exception : IA , IIA , Al3+ , Zn2+ , Ag+

Naming Simple Compounds IUPAC - II

3. Polyatomic ions1) NH4NO3 NH4

+ + NO3-

2) Table 2.5 (memorized !!)

3) O : hypo- / -ite / -ate / per-

4. Binary compounds (Type III ; covalent : nonmetals)– see p.39-40 for rules & examples

– H2O (water) , NH3 (ammonia) , CH4 (methane)

Chapter 1 Chemical Measurements

• Microelectrode by Optical Micrograph

SI units

Ex: Exocytosis of Neurotransmitters

• ppm = 106(mass of substance/mass of sample)• ppb = 109(mass of substance/mass of sample)

• 1ppm ～ 1ug/mL

• 1ppb ～ 1 ng/mL
