Hydrochloric acid 0.05% is a weakly concentrated solution used in various scientific and technical fields. In medical diagnostics, histology and life sciences, it is mainly used as a buffer solution to adjust the pH in various experiments and assays.

The special suitability of this dilute hydrochloric acid solution lies in its ability to precisely control the pH of a solution. This makes it possible to create optimal conditions for enzymatic reactions, protein purification or cell culture procedures. The low concentration helps minimize undesirable side effects that can result from stronger acid concentrations.

Chemically, hydrochloric acid is a strong inorganic acid with the formula HCl. In dilute form, as in a 0.05% solution, it is a weak acid that affects the pH of a solution by protonating or deprotonating molecules. The way hydrochloric acid works is based on its ability to donate protons (H+) to the surrounding molecules.
