Chemists have known for centuries that certain elements react predictably when combined. When considering whether you can mix copper and iodine together, an immediate and visually striking redox reaction occurs, resulting in the formation of copper(I) iodide and the release of elemental iodine. This process is a classic chemistry demonstration that highlights key principles of oxidation and reduction.

According to the Office of Environmental Health Hazard Assessment (OEHHA), people are generally exposed to low amounts of methanol from certain consumer products. This guide details what products have methanol in them and explains the context of its use, which is critical for safety.

While hydrochloric acid in the stomach aids digestion, many other acids pose severe risks to human health, with hydrofluoric acid being among the most dangerous due to its unique ability to cause systemic poisoning and deadly cardiac arrhythmias. The question of which acid is not good for humans is best answered by highlighting those with extreme corrosive properties and additional systemic toxicity, not just those that cause surface burns.
