The Chemistry of Cyanide Poisoning and Why it Kills

Sep 12, 2018The symptoms of cyanide poisoning are similar to those displayed by other conditions or exposure to any of a number of chemicals, so don't assume cyanide is the cause. In any event, do remove yourself from the cause of exposure and seek immediate medical attention.

PPM vs Efficacy Colloidal Silver Generator

PPM of colloidal silver needs to be understood in its entirety. PPM means parts per million. By definition 1 PPM is 1 milligram of silver deposited in 1 liter of water (1,000 ml) (1,000,000 mg). If one were to ingest that 1 mg. piece of silver, it would not do much good.

Potassium is weakly hazardous in water, but it does spread pretty rapidly, because of its relatively high mobility and low transformation potential.
