JSP NITRIC ACID 69.8% 32OZ BOTTLE & JSP ONE HYDROCHLORIC ACID 31% 16OZ Nitric acid is a strongly corrosive mineral acid with a suffocating odor. It appears as a colorless liquid at room temperature but can appear yellow upon decomposition into oxides of nitrogen and water. Our Lab/Technical grade Nitric Acid (69.8%) can be used in commercial applications and research labs, but due to its unknown impurities, it cannot be used in food items, drugs, and medicines. It is considered the strongest acid due to its low pH and highly reducing nature. These are ACS Regent grade acids typically used for making Aqua regia.  Directions for making Aqua Regia: Always wear proper PPE when handling acids.
