Acid-base titration

The rapid development of knowledge in the natural and social sciences - same day essay - confronts us all with new questions every day. Hardly a day goes by without criminology searching for traces of endogenous substances and toxins, environmental research for contamination in air and water, medicine for substances that control or harm our bodies.

Food and household chemicals such as cleaning agents contain different acids and bases - solve chemistry problems . The acid content is crucial for the taste and shelf life of food and the cleaning effect of a descaler and is therefore constantly controlled by the manufacturers. The analytical methods for this are becoming more and more sophisticated, reliable, meaningful and accurate.

In this context, the clients are interested not only in the question - https://domyhomework.club/ : "What is present in the samples?" (question of quality), they are also interested in "how much of it is there? (question about quantity).

A simple and yet very reliable method of quantitative analysis is titration, which has been used for a very long time to determine the concentration of aqueous solutions. The name is derived from the French term for content (French: titre = content).

Principle of titration

Titrations are based on the following basic principle:

1. a precisely measured portion of the sample to be analysed is dissolved in a precisely defined volume of solvent (usually water). The analysis solution thus obtained now contains the titrant, i.e. the substance to be determined.

2. a standard solution (solution with a known concentration) containing the titrator is added to this analysis solution by stirring or shaking it slowly and carefully.

3. the two solutions react with each other in a known reaction. The dripping of the measuring solution into the analysis solution is carried out with the aid of a burette until the equivalence point of the reaction is reached.
