a) Usoro kemịkalụ:

Jiri tapawa pickling ma ọ bụ fesa iji nyere akụkụ ndị tara akpụ aka ka ha megharịa ma mepụta ihe nkiri chromium oxide iji weghachi nguzogide corrosion.Mgbe ịchachara, ọ dị ezigbo mkpa iji mmiri dị ọcha saa nke ọma iji wepụ ihe niile na-emerụ emerụ na ihe fọdụrụ na acid.Mgbe ọgwụgwọ niile gasịrị, jiri ngwá ọrụ na-egbuke egbuke mee ka ọ dị mma ọzọ ma jiri wax na-egbuke egbuke mechie.Maka ndị nwere ntakịrị ntụpọ nchara n'ógbè ahụ, ngwakọta nke mmanụ ụgbọala na mmanụ injin 1: 1 nwere ike iji akwa dị ọcha kpochapụ ntụpọ nchara.

b) Usoro igwe:
