Answer
Ruwan ruwa na hydrogen yana faruwa ne a lokacin da ake tattara acid ko na lantarki (misali, Zinc plating) na maɓuɓɓugan ƙarfe na ƙarfe mai ƙarfi. Atomic hydrogen ($H$) yana bazuwa cikin iyakokin hatsi na karfe. Ƙarƙashin damuwa mai ƙarfi, waɗannan atom ɗin hydrogen suna ƙaura zuwa ƙwanƙolin ƙananan fasa, suna rage ƙarfin haɗin gwiwa na lattice da haifar da karaya a damuwa mai nisa ƙasa da ƙarfin amfanin gona. Don rage wannan, dole ne a 'gasa maɓuɓɓugan ruwa' nan da nan bayan plating (yawanci akan $375^{\circ}F$ na awa 4 zuwa 24 dangane da kauri) don fitar da hydrogen ɗin da aka kama. Rashin gazawa yawanci yana nunawa azaman tsaftataccen farfajiya, 'kamar gilashi' ba tare da wata shaidar nakasar filastik ba.
