Ammonium Hydroxide 1.0N Standardized Solution

Ammonium Hydroxide, NH4OH, is formed when ammonia (NH3) is dissolved in water. Ammonia deprotonates a small portion of water molecules leaving the free hydroxide ion, [OH]-, to form a slightly basic solution. The resulting solution is clear, colorless, with a pungent odor and vapors that may irritate the eyes.Ammonium Hydroxide, 0.1N solution contains 6.19 mL of Ammonium Hydroxide solution (56% w/w) in 1000 mL Deionized Water. It is a mild solution that contains just 0.62% concentration of Ammonium Hydroxide. For the measurement of total iodine (m/z 127) in baby formula and adult nutritional goods, an ammonium hydroxide solution is utilized to create a single-laboratory validation using inductively coupled plasma-mass spectrometry.
