I then forgot about chemistry for a few years. When I about ten, my dad bought me a cool little micro-set. It came with about 40 different
reagents, about 1 gram each. I was fascinated with the fact that on the bottles was an overzealous warning about toxicity. COBALT CHLORIDE--EXTREMELY
POISONOUS. Yeah right! The LD50 is 80 mg/kg, thus I would need about five bottles of it to maybe kill me. |
