A mixture of O2 and ethyne is used for welding purpose. Can you tell why a mixture of ethyne and air is not used?
Asked by subbukum | 04 Feb, 2020, 11:46: AM
Mixture of ethyne and air cannot be used due to hazard associated with ethyne's intrinsic instability; samples of concentrated or pure acetyle will explosively decompose in air. Acetylene can explode with extreme violence if the pressure of the gas exceeds about 200 kPa (≈39 psi) as a gas or when in liquid or solid form.
