Hydrogen stress cracking is the same mechanism that is responsible for sulfide stress corrosion cracking in wet H₂S environments except that HF acid is generating the __________.

Question

Quizplus · Accepted Answer

Hydrogen stress cracking is caused by the absorption of hydrogen atoms by a metal, which can lead to embrittlement and cracking. In the case of HF acid exposure, the hydrogen atoms are generated by the acid reacting with the metal. Sulfide stress corrosion cracking, on the other hand, is caused by the reaction of hydrogen sulfide gas with the metal, leading to the formation of hydrogen atoms on the metal surface. Therefore, the correct answer is C, as HF acid generates hydrogen.
