  1. All users of hydrochloric acid must review this document. Hydrochloric acid is a strong acid and a highly corrosive liquid. This chemical compound is the aqueous (water-based) solution of hydrogen chloride gas. 36% hydrochloric acid is highly volatile and is a high-risk inhalation hazard.

  2. a 0.5M solution can be prepared by a 1 part in 2 dilution of the 1M solution, a 0.1M solution by a 1 part in 10 dilution of the 1M solution, and a 0.01M solution by a 1 part in 10 dilution of the 0.1M solution.

  3. Hydrochloric acid is used in the chemical industry as a chemical reagent in the large-scale production of vinyl chloride for PVC plastic, and MDI/TDI for polyurethane. It has numerous smaller-scale applications, including household cleaning, production of gelatin and other food additives, descaling, and leather processing. Colorless liquid.

  4. What are the hazards? What is the chance of something going wrong? eg hazardous products (such as chlorine) produced as a result of a reaction with the acid or choking fumes if the concentrated acid is over-heated. How serious would it be if something did go wrong?

  7. therefore, these solutions require different classification and labelling since the hazards vary at different concentra-tions. In Part 3 entries with Note B have a general designation of the following type: ‘nitric acid ... %’. In this case the supplier must state the percentage concentration of the solution on the label.
