Help Hydrogen Sulfide route

Are you planning a big suicide party for 100+ guests?

You seem to want to CTB in the most difficult way. If I planned to decompose 1 liter of formic acid for whatever reason, I'd mix the acids gradually for safety. I wouldn't do this for suicide though. Making 2 - 4 liters of CO should suffice for this purpose. Using citric acid + sulfuric acid seems the most appealing method for me because of the lowest risk of exposure to irritating fumes.

1. well enough hcn for me In a car . how would I make sodium cyanide or potassium cyanide safely.

1. well enough hcn for me In a car .

IDK what would mean "enough" in a car. From what I've read, effectively working concentrations of HCN are close to those for H₂S. ≥1000 ppm is a must, and ≥2000 ppm would be better. 500 - 600 ppm seem insufficient for quick fainting.

Reaching sufficiently high concentrations in a large confined space may take minutes depending on how much reagents you mix and how much you heat them. Prolonged exposure to concentrations that are insufficient for quick LOC may produce unpleasant symptoms.

Two possible reactions for making HCN are mentioned here

If you wanna experiment, good luck.

how would I make sodium cyanide or potassium cyanide safely.

Safely? No idea
