Tasks
1. Are the sentences true (T) or false (F)?
1. Qualitative analysis seeks to establish the amount of a given element or compound
in a sample.
2. Most modern analytical chemistry is quantitative.
3. Separation is a technique used to determine amounts present in solution or a
physical characteristic of a molecule such as an equilibrium constant.
4. Qualitative organic analysis seeks to establish the presence of a given functional
group in a sample.
5. Techniques which combine two or more analytical methods are sometimes called
"hyphenated" methods.
6. Mass spectrometry is used to determine the molecular mass and structure of
chemical species.
7. An equilibrium constant can be determined using such a technique as titration.
8. The method of addition is used when the amount in the sample is below an
instrument's range of measurement.
9. The method of spectroscopy enables to analyze the chemical species without
separation.
10. Analytical chemistry research is largely driven by performance and cost.
2. Give the English equivalents to the Russian words and word-combinations.
Широкий спектр применения; новейшие достижения;
производство лекарств; установить присутствие данного элемента;
изумительное множество методов; современные методы
