Why Not Use Potassium Chlorate for Oxygen Production?

Potassium chlorate is not commonly used for oxygen production due to several drawbacks. Firstly, it is highly unstable and can decompose into oxygen and potassium chloride at relatively low temperatures, posing a significant safety risk. Secondly, the decomposition process is not efficient, resulting in a low yield of oxygen. Lastly, the byproduct, potassium chloride, is a hazardous substance that requires proper disposal.

The instability of potassium chlorate is a major concern. According to a study by the National Institute for Occupational Safety and Health (NIOSH), potassium chlorate can decompose into oxygen and potassium chloride at temperatures as low as 200°F (93°C) (NIOSH, 2019). This poses a risk of explosion or fire, especially in confined spaces or when mixed with other chemicals. In contrast, other oxygen-producing agents like hydrogen peroxide or potassium perchlorate are more stable and safer to handle.

Moreover, the efficiency of potassium chlorate in producing oxygen is low. When potassium chlorate decomposes, it yields only about 33% oxygen by weight (Wikipedia, 2021). This low yield makes it an inefficient choice for oxygen production, especially in industrial applications where large quantities of oxygen are required. For instance, hydrogen peroxide can produce oxygen at a yield of up to 68% (Wikipedia, 2021), making it a more attractive option.

The byproduct of potassium chlorate decomposition, potassium chloride, is also a concern. Potassium chloride is a hazardous substance that can cause environmental damage if not disposed of properly. It can contaminate water sources and soil, leading to ecological imbalances. In contrast, the byproducts of other oxygen-producing agents, such as water and salt, are less harmful to the environment.

In conclusion, potassium chlorate is not suitable for oxygen production due to its instability, low efficiency, and hazardous byproduct. Other oxygen-producing agents offer safer, more efficient, and environmentally friendly alternatives.
