 Appearance Clear, Trace Yellow • NITRIC ACID is highly corrosive to human tissue.
 • ALWAYS wear liquid impervious clothing, gloves and boots.
 Specific Gravity @20°C (68oF) (g/cc) 1.363 --
 • ALWAYS protect eyes and face with shield when loading.
 Freeze Point -22°C (-8°F) --
 • NITRIC ACID has a high vapor pressure and begins to vaporize into a white fume at
 warm ambient temperatures. Breathing high concentrations of the fume can cause
 severe respiratory problems.
 • NEVER use NITRIC ACID as a substitute where mineral acids are typically used.
 Hazardous Shipping Description

TECHNICAL DATA SHEET
NITRIC ACID PRODUCT DESCRIPTION
 NITRIC ACID is created by oxidizing anhydrous ammonia
Tower Acid over a platinum catalyst at extreme temperatures. The resultant gases, nitric oxide and
 nitrogen dioxide, or 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
 SDS present in the water source used for absorbing the acid gas or in the compressed air used
 Properties #1023
 in the process. The product acid is clear and colorless to slightly yellow. The common
 yellow discoloration in NITRIC ACID is directly proportional to the level of oxides of nitrogen
 dissolved in the solution. This is HNO2 or nitrous acid. It can be minimized using various
 Typical Analysis Specifications techniques from process air bleaching to inert chemical addition. The acid is miscible with
 water in all portions accompanied with a rise in temperature. Nitric Acid % 57 55.0 - 59.0
