Hydrochloric Acid 3 %

Hydrochloric acid 3 %, consisting of a solution of hydrochloric acid (HCl) in ultrapure water, can be used in many chemical and biological laboratory applications. In medical diagnostics it is used to change the pH of solutions, while in histology it is used to decalcify tissue samples. Due to its chemical formula HCl, hydrochloric acid is characterized by its strong acidic property. It can accept electrons from other compounds and donate protons, contributing to chemical reactions. In metallography, hydrochloric acid is used to etch metals to highlight their microscopic structures. The use of this solution leads to precise and reproducible results by modifying the chemical properties of samples and facilitating their analysis.
