Potassium nitrite is a strong oxidizer with the chemical formula KNO2. High levels of potassium nitrite in the blood causes methemoglobinemia & its associated symptoms, headache, fatigue, dizziness, blue coloration to the skin & lips, due to the binding of the nitrite ion to blood cells, reducing their ability to carry oxygen. Sufficiently high levels can cause respiratory depression, collapse, and death. Potassium nitrite shares a method of action with sodium nitrite, but it takes more of the product to achieve the same effect. Its molar mass is approximately 85 g/mol. The molar mass of SN is approximately 69 g/mol. This is where the 85:69 dosing ratio comes from. However, LD 50 of potassium nitrite is cited at 235 mg/kg. Potassium nitrite is very soluble in water. At 0°C it's soluble at 281 g/100 mL, at 25°C at 312 g/100mL, and at 100°C at 413 g/100 mL. This is more soluble than sodium nitrite who at 25°C is 84.8 g/100 mL soluble. So while more potassium nitrite is required, less water is needed to dissolve it. It is also soluble in alcohol. Potassium nitrite is on the hazardous substance list because while not combustible itself, it may enhance combustion of other substances. It is non-flammable but explodes at 537°C. Overall, it is less ideal than its counterpart sodium nitrite, but in some locations it may be easier to source. I personally am still able to find it through a major online retailer. Less water is needed, which is nice. However, it would require more product, and your body rejects them mixture due to the amount of salt required. An equivalent dose of potassium nitrite to 25 g of SN would be about 31g. An extra 6g of salt may seem insignificant, but I feel it would probably increase the chances of vomiting even with an AE. I have access to online medical journals & make look into more research about it. It seems like an alternative for SN that would have more issues with keeping it down, but I figured the math on it might be interesting
