Convert to 15% out of the whole course Note: If absent during lab session, no marks given for lab reports.

Before entering lab
# Study the experiments # Do related reading and calculations

At start lab session
- Identify workspace and reagents/apparatus

During lab session
* Careful * Think scientifically * Record results, observation

Completing lab End of lab
# Compile results into data sheets - Submit report 2 weeks after lab session - Before starting new lab session

Important points


Reports submission (per group) at the start of each lab session. Record all results and observation in data sheets. Reports submission (per group) 2 weeks after lab session.

 




Wear shoes in the lab (no slippers/ sandals!!).
Bring your lab coat and wear it in the laboratory at all time.

Important points


If you have long hair, bring a hair tie and tie your hair back before the beginning of your laboratory session.



Before your lab ends for the day, always clean up spills and carefully clean lab equipment. Make sure you wash your hands before the end of your laboratory session. Use soap and make sure you have gotten all substances off your skin.

Definition


Analytical chemistry is a metrological science that develops, optimizes and applies measuring processes intended to derive quality chemical information of both global and partial type in order to solve the measuring problems posed. Valcácel, M. (1997) A modern definition of analytical chemistry. Trends in analytical chemistry, 16 , 124-131)

Definition
The definition implies: 1) analytical chemistry as the science of measurements; 2) it possesses a dual character: basic (‘it develops’) and practical (‘it applies’); 3) it delivers information about the material or system studied; 4) it regards measuring processes that can be called ‘analytical processes’ as the vehicles for obtaining information; 15

Analytical Chemistry


Qualitative analysis – Identifying the chemicals present in the sample. E.g. What are found in your drinking water – Fe, Zn.



Quantitative analysis – Separating, identifying and quantifying the relative amounts of the components of an...
