Air-reactive chemicals are substances that can undergo a chemical reaction upon exposure to air or atmospheric oxygen. Among the provided options, phenols are classified as air-reactive due to their ability to oxidize when they react with oxygen in the presence of moisture. This oxidation can lead to the formation of various byproducts that may be hazardous.

While oxidizers indeed react with oxygen and can be dangerous, they are not solely defined as air-reactive chemicals. Oxidizers may require additional conditions to induce a reaction or can be stable under certain circumstances. Anionic compounds and salts typically don’t react with air in a way that poses an immediate risk, making them less relevant to the definition of air-reactive substances.

The focus on phenols highlights their potential risk in laboratory settings, especially when handled improperly, reinforcing the significance of lab safety protocols surrounding air-reactive chemicals. Understanding these characteristics is crucial for maintaining a safe laboratory environment and preventing accidents associated with uncontrolled reactions.
