NITRIC ACID 67%
Document type: Tech Info
Categories: Industrial Chemicals

Product Description
NITRIC ACID is created by oxidizing anhydrous ammonia over a platinum catalyst
at extreme temperatures. The resultant gases, nitric oxide and nitrogen dioxide, or Typical Analysis Specification
NOx, are cooled and absorbed into demineralized water. Apart from the hydrogen
and nitrate ions, NITRIC ACID will not contain any ions unless they were present in Nitric Acid % 67.5 67.0 - 67.9
