What is the explosive range of Hydrogen?

The explosive range of hydrogen is correctly identified as being from 4.1% to 74%. This range indicates the concentration of hydrogen in air that can lead to combustion when mixed with oxygen and exposed to an ignition source. The lower limit of 4.1% signifies the minimum concentration of hydrogen needed for an explosive mixture, while the upper limit of 74% indicates the maximum concentration before the mixture becomes too rich to ignite.

Understanding this explosive range is crucial for ensuring safety in environments where hydrogen is present, such as in laboratories or industrial settings. Proper awareness of these limits helps in implementing safety measures and protocols to prevent potential explosions or fires.
