I'm plotting a murder mystery to follow the one I posted in GD. This one has a chemistry aspect to it. It won't involve some esoteric, complex hydrocarbon or anything like that, but there's a chemical reaction that needs to happen and I don't remember enough chemistry to set it up. Any volunteers would be very helpful. |

If they even bother with it, otherwise they run a line and pump you full of 5% dextrose while they figure out what's happening. Besides, it isn't cool. I want the corpse to go on fire. Fire is cool. I might even have him wear a Metallica t-shirt when he does it. |

I'm thinking about a .38 Special jacketed bullet with the lead removed. He fills it with potassium and closes the base with wax and steel wool to aid in ignition. He does this because he's making an impression, not because he thinks it will be more deadly that way. I know the K will react with water in the body, but I want the reaction to be noteworthy.

A few grains of it won't be. Even sodium, which is more reactive, isn't really that spectacular in that amount in pure water. |

A 158 grain .38 would be a bit under 1/4 ounce of reactant and he'd empty the cylinder.
I was looking at cuprous potassium cyanide, possibly with a wax seal embedded with powdered steel wool or magnesium to help light it. I was hoping to use a Raven MP25 as the murder gun, but the .25 won't work. I want the gun to be a real turd. An RG .38 would be perfect. I think I'm going to have to find my friendly, neighborhood chemistry professor and bribe this person with a free lunch to work through this. |

If you use potassium cyanide instead of potassium metal the cyanide ion bonds to a transport enzyme in the aerobatic production of ATP in the mitochondrial wall. That shuts down the cells energy burning process and is similar to suffocation. ETA: Tag in case there are more chemistry questions. |

Potassium is more reactive than sodium. Group IA elements, otherwise known as alkali metals, become more reactive as you move down the periodic table and electronegativity goes down. Here is your reaction: 2K (s) + 2H2O (l) -> 2KOH (aq) + H2 (g) + Heat Quote HistoryQuoted:

I recalled the lighter ones being more reactive. |

1) make entry to target residence. 2) wet the carpet behind the steel entry door. 3) place thin magnet wire under or on wet carpet. 4) reeve thin wire thru bottom of entry door. 5) use and old-school television transformer secondary, and plug into outdoor outlet. "after it's done", pull the wire back out from behind the locked door, and the carpet dries naturally, guy dies from Vfib behind locked door. CSI have to conclude cardiac arrest. there is a simpler variation on this where you don't need to make entry; wet the carpet outside the door, tie transformer secondary to doorknob. it's not as solid a story as the first method but it does avoid the need to make entry of the target residence. please let me know when my first check will arrive. ar-jedi |

However, unless he is storing in under oil, it will react with the moisture in the air and be KOH before he uses it. Also, it will sputter, produce some hydrogen, and saponify the fat around it, but not do a lot. |

ar-jedi Very pure water (AKA 'de-ionized') is a good enough insulator to be used in discharge machining tanks. The ionic contaminants in water are what makes it a conductor. At cyclotrons we used to make large secondary wires using copper tube. By circulating de-ionized water we could cool the windings with no significant current leakage through the water. |

It's the whole "bursting into flames after being shot with an incendiary bullet" thing that's preventing us from providing a solid response. Problem is the mass (volume) of anything incendiary enough to produce the desired effect simply won't fit in anything smaller than 20mm or so. If it did, gunshot combatants would already be bursting into flame on battlefields all over the world.
I was pretty excited when I read the title of this thread. But I gotta say, these limitations I just can't work with... How bout a nice poison? |
