• Disposal Method:
  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. Prepare a 0.5 M sodium hydroxide solution and dissolve the sodium sulfide compound in the solution.
    a. Use about 100 mL NaOH for every 10 mL of sodium sulfide
   2. Slowly add sodium hypochlorite solution (bleach). Add 200 mL bleach for every 5 mL of sodium sulfide.
   3. After allowing the solution to sit overnight, flush the mixture down the drain with at least a 20-fold excess of water.
• Solution Preparation:
  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.
