Disposal

This disposal method is published for your convenience. You MUST have checked with your federal, state, and local regulations before using this method and these methods are only applicable for small laboratory sized quantities.

Use a lab apron, chemical resistant gloves and goggles before following the below method to dispose of hazardous waste.

 1. Add the substance to be disposed of to a large beaker and dissolve it in an excess of water. Place the beaker in a fume hood.
 2. Add a 50% molar excess of ammonium hydroxide (ammonia) to the nitrite solution.
 3. Acidify the solution using 3 M hydrochloric acid until the solution has a pH of 1.
 4. Neutralize the resulting mixture with dilute sodium hydroxide to a pH of about 7.
 5. Pour the final solution down the drain with at least a 20-fold excess of water.

Solution Prep

To prepare a solution, determine the formula weight of the material, the concentration (Molarity) of the solution, and the amount of solution desired in Liters. Once this information has been obtained, use the following formula:
(Formula Weight) x (Concentration) x (Desired Volume) = Number of grams in desired volume of liquid

For a 1 M, 1 L solution:
(Formula Weight) x (1 mol/L) x (1 L) = x g added to 1-L volumetric flask. Dilute to a final volume of 1 L with DI Water.
