I. Chemistry and medicine

1. Subject, goals and objectives of analytical chemistry. A brief historical sketch of the development of analytical chemistry. The place of analytical chemistry among the natural sciences and in the medical education system.

Analytical chemistry – the science of methods for determining the composition of substances. Item its - solving general problems of the theory of chemical analysis, improving existing and developing new, faster and more accurate methods of analysis (i.e. the theory and practice of chemical analysis). Task - development of the theory of chemical and physicochemical methods of analysis, processes and operations in scientific research, improvement of old methods of analysis, development of express and remote MA, development of methods of ultra- and microanalysis.

Depending on the object of study, analytical chemistry divided into inorganic and organic analysis. Analytical chemistry refers to applied sciences. Its practical significance is very diverse. Using methods of chemical analysis, some laws were discovered - the law of constancy of composition, the law of multiple ratios, the atomic masses of elements were determined,

chemical equivalents, chemical formulas of many compounds have been established, etc.

Analytical chemistry greatly contributes to the development of natural sciences: geochemistry, geology, mineralogy, physics, biology, agricultural chemistry, metallurgy, chemical technology, medicine, etc.

Subject of qualitative analysis- development of theoretical foundations, improvement of existing ones and development of new, more advanced methods for determining the elemental composition of substances. The challenge of qualitative analysis- determination of the “quality” of substances or detection of individual elements or ions that make up the compound under study.

Qualitative analytical reactions according to the method of their implementation are divided into reactions “wet” and “dry” way. Reactions by the “wet” route are of greatest importance. To carry them out, the test substance must first be dissolved.

In qualitative analysis, only those reactions are used that are accompanied by any external effects clearly visible to the observer: a change in the color of the solution; precipitation or dissolution of sediment; release of gases with a characteristic odor or color.

Reactions accompanied by the formation of precipitation and a change in the color of the solution are especially often used. Such reactions are called reactions "discoveries”, since with their help the ions present in the solution are detected.

Reactions are also widely used identification, with the help of which the correctness of the “discovery” of a particular ion is verified. Finally, precipitation reactions are used, which usually separate one group of ions from another or one ion from other ions.

Depending on the amount of the substance being analyzed, the volume of the solution and the technique for performing individual operations, chemical methods of qualitative analysis are divided for macro-, micro-, semi-micro and ultra-microanalysis and etc.

II. Qualitative analysis

2. Basic concepts of analytical chemistry. Types of analytical reactions and reagents. Requirements for analysis, sensitivity, selectivity in determining the composition of substances.

Analytical reaction - chem. a reaction used to separate, detect and quantify elements, ions, molecules. It must be accompanied by an analytical effect (precipitation, gas release, color change, odor change).

By type of chemical reactions:

Are common– analytical signals are the same for many ions. The reagent is general. Example: precipitation of hydroxides, carbonates, sulfides, etc.

Group– analytical signals are characteristic of a certain group of ions with similar properties. The reagent is a group one. Example: precipitation of Ag +, Pb 2+ ions with the reagent - hydrochloric acid with the formation of white precipitates AgCl, PbCl 2

General and group reactions are used to isolate and separate ions of a complex mixture.

Selective– analytical signals are the same for a limited number of ions. The reagent is selective. Example: when the NH 4 SCN reagent acts on a mixture of cations, only two cations form colored complex compounds: blood red 3-

and blue 2-

Specific– the analytical signal is characteristic of only one ion. The reagent is specific. There are very few such reactions.

By type of analytical signal:

Colored

Precipitative

Gas-emitting

Microcrystalline

By function:

Detection (identification) reactions

Separation (separation) reactions to remove interfering ions by precipitation, extraction, or sublimation.

By technique:

Test tube– will be performed in test tubes.

Drip are executed:

On filter paper

On a watch glass or slide.

In this case, 1-2 drops of the analyzed solution and 1-2 drops of a reagent that gives a characteristic color or the formation of crystals are applied to a plate or paper. When performing reactions on filter paper, the adsorption properties of the paper are used. A drop of liquid applied to paper quickly dissolves through capillaries, and the colored compound is adsorbed on a small area of ​​the sheet. If there are several substances in a solution, their speed of movement can be different, which gives the distribution of ions in the form of concentric zones. Depending on the solubility product of the precipitate - or depending on the stability constant of complex compounds: the greater their values, the closer to the center or in the center a certain zone is.

The drop method was developed by the Soviet chemist N.A. Tananaev.

Microcrystalline reactions are based on the formation of chemical compounds that have a characteristic shape, color and light refractive ability of crystals. They are performed on glass slides. To do this, apply 1-2 drops of the test solution and 1-2 drops of the reagent next to a clean glass with a capillary pipette, carefully combine them with a glass rod without stirring. Then the glass is placed on a microscope stage and the sediment formed on the spot is examined.

contact of drops.

For proper use in reaction analytics, one should take into account reaction sensitivity . It is determined by the smallest amount of the desired substance that can be detected by a given reagent in a drop of solution (0.01-0.03 ml). Sensitivity is expressed by a number of quantities:

    Opening minimum- the smallest amount of substance contained in the test solution and opened by a given reagent under certain reaction conditions.

    Minimum (limit) concentration shows at what lowest concentration of solution this reaction allows one to unambiguously discover the detected substance in a small portion of the solution.

    Limit dilution- the maximum amount of diluent at which the substance can still be determined.

Conclusion: The analytical reaction is more sensitive, the lower the opening minimum, the lower the minimum concentration, but the greater the maximum dilution.
