Hydrochloric acid 5.0 mol/l is used in numerous applications due to its strong acidic effect. In analytical chemistry, it is often used as a titration solution for the determination of bases and alkali metals. It is also used in life science to adjust pH values in various solutions and buffer systems.

The special suitability of this hydrochloric acid concentration lies in its high reactivity and ability to provide precise pH changes in chemical reactions or solutions. Providing an accurate pH range allows researchers to produce optimal conditions for biochemical processes.

Chemically, hydrochloric acid 5.0 mol/l is an aqueous solution of hydrogen chloride (HCl). Its strong acidity results from the complete dissociation of HCl in water, releasing protons (H+) and chloride ions (Cl-). The proton concentration determines the pH of the solution and allows chemical reactions to be selectively influenced.

Compared to other acids, hydrochloric acid 5.0 mol/l offers an excellent combination of reactivity and manageability. It is capable of supporting numerous chemical reactions and processes, particularly in histology, medical diagnostics and life science, while presenting fewer hazards than more concentrated acids.
