The setup, useful for schools and universities, includes a Geiger counter that can measure the number of detected particle collisions. The user can choose among different radioactive sources, as well as an absorber to put between the radioactive source and the probe. Additionally, other parameters that users can vary are the distance and number of tests. This allows for a wide range of experiments and learning opportunities.

The acidity of soils can occur due to various processes that promote a pH reduction. These processes occur naturally or by human action. The main sources of soil acidity are associated to hydrogen ions (H+) and aluminum ions (Al+3) in the soil's solution. Exchangeable acidity is determined through the use of neutral salts solutions such as potassium chloride (KCl). The acid ions (aluminum and hydronium) that are held in the colloidal fraction of the soil, that in the presence of a displacing ion (K+), makes those enter the soil solution. Afterward, that solution is titrated with a sodium hydroxide solution of the exact concentration to reach the last point of the neutralization reaction using phenolphthalein as an indicator.

In this version of the laboratory (Acid-Base Titration II) you can perform the acid-base titration for an unknown hydrochloric acid solution. In other versions of the laboratory you can perform the acid-base titration for a citric acid solution instead (Acid-Base Titration I), and acetic acid (Acid-Base Titration II).

Both this version of the laboratory (Acid-Base Titration III) and Acid-Base Titration II emphasize visual burette measurements, including properly reading the meniscus in the burette. The other version of the laboratory (see Acid-Base Titration I) does not emphasize this, and focuses on the calculations instead.

Also, in these versions you can choose between two different configurations: one for the potentiometric approach and one for the colorimetric approach. The configuration for the colorimetric approach does not show the pH sensor. In other version of the laboratory (see Acid-Base Titration I) there is a single configuration and the sensor is always shown.
