Reagent hydrochloric acid is a strong acid that can react with basic substances to form salts and water. It is widely used in chemical reactions as a proton donor, pH adjuster, and catalyst. However, it is necessary to control its concentration and dosage during use to avoid interfering with the experiment. Additionally, reagent hydrochloric acid can be used for passivation of metal surfaces to prevent corrosion. Nevertheless, safety measures such as avoiding skin, eye, and respiratory exposure, and promptly seeking medical attention in case of contact, should be taken into consideration.

In conclusion, reagent hydrochloric acid is an essential reagent in laboratory experiments, and its quality and performance can significantly influence the accuracy and stability of experimental results. We recommend choosing Xi'an Sanpu's product for its high purity, superior performance, and sustainable development.
