The JSP® Hydrochloric Acid 31% (500ml, 16oz) is a high-purity, industrial-grade acid essential for gold refining, aqua regia preparation, and metal cleaning. This listing is for a single 16oz bottle of technical-grade hydrochloric acid, widely used in jewelry-making, metal refining, and laboratory applications.

This colorless, highly corrosive solution reacts with base compounds to form dissolved chlorides, making it crucial for etching, dissolving oxides, and preparing metals for analysis. It is also a key component in creating Aqua Regia, a powerful gold-dissolving solution when mixed with nitric acid (sold separately).

Directions for Making Aqua Regia:

1. Place gold in a heat-resistant beaker with JSP® Hydrochloric Acid 31%.
2. Slowly add Nitric Acid to the solution.
3. Stop adding nitric acid when the reaction ceases.
