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 solid barium salt in a minimal amount of water.
 2. Add 3 M sulfuric acid to the solution via a pipet. Add the sulfuric acid until the precipitation is complete.
 3. After the precipitate has settled, decant the supernatant liquid.
 4. Neutralize the acidic liquid with sodium carbonate. The solution will be neutral once gas evolution stops.
 5. The precipitate needs to be collected and disposed of in an approved container for a landfill.

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.
