a) The Acid Conversion Test (ACT)
Nembutal that is to be taken to achieve a peaceful death needs to be in the form of the soluble salt, sodium pentobarbital. When dissolved in water the salt forms a clear alkaline liquid (with pH ~10) which explains the bitter taste. Conversion into the insoluble crystalline form can be readily achieved by acidifying the solution and driving the pH down, so that a precipitate is formed. If the original salt sample is 100% pure sodium pentobarbital, the weight of the precipitate formed should be 90% of the original. In other words if one dissolves 200mg of 100% pure Nembutal powder, acidifies, separates, dries and weighs the precipitate, one would expect a weight of 180mg.
