Is potassium nitrate gas poisonous?
Potassium nitrate itself is not poisonous. However, when heated to high temperatures, it can decompose and release toxic gases, including nitrogen dioxide, which can be harmful if inhaled in high concentrations. It is important to handle and store potassium nitrate safely and avoid exposure to its decomposition products.
