Aqueous. 10% v/v.
This non-concentrated solution is 10 percent reagent grade nitric acid and ninety percent deionized water, measured volume to volume.
A 10% nitric acid solution is commonly used as a cleaning product while sanitizing food and beverage processing equipment and also for metal surface treatment. A weak solution of nitric acid is also used by woodworkers to "pop" the grain of curly maple.
Since nitric is very effective in the removal of tough mineral deposits, we recommend this 10% solution to be used when preparing copper, bronze, or brass for chemical patina. A soaking in 10% nitric acid serves to remove any traces of surface dirt or oil.
For shipping, Nitric Acid is in hazardous materials Class 8: Corrosive Substances. It only ships to destinations within the 48 contiguous US states using Standard Ground. A HazMat fee applies. Adult signature required upon delivery. Shipping to a commercial address is suggested.
