IV. Usoro mgba ọkụ

Ekwesịrị ịchekwa sodium hydrosulfide n'ụlọ nkwakọba ihe dị jụụ, nke nwere ikuku nke ọma, pụọ na isi mmalite nke mgbanye na okpomọkụ. Ekwesịrị ịchekwa ya iche site na oxidizers na acids, ma amachibidoro ịgwakọta ya nke ọma. Kwadebe ebe nchekwa ahụ na ụdị kwesịrị ekwesị na ọnụ ọgụgụ nke ngwá ọrụ ọkụ ọkụ na mgbapụ ngwaọrụ nzaghachi mberede. Ebe nchekwa ahụ kwesịrị inwe ihe kwesịrị ekwesị iji nwee ntapu ọ bụla.

V. Nzaghachi mberede nye ntapu

Kewapụ mpaghara ntapu emeru ma gbochie ohere. A dụrụ ndị na-aza ihe mberede ọdụ ka ha yi akwa mkpuchi uzuzu (ihu zuru oke) na uwe nchebe acid-alkali. Amachibidoro kọntaktị na akpa gbajiri agbaji na ihe ndị gbawara agbawa ruo mgbe eyiri uwe nchebe kwesịrị ekwesị. Bipụ isi iyi ahụ ma ọ ga-ekwe omume. Maka obere ntapu: zere ọgbọ uzuzu ma jiri shọvel dị ọcha nakọta ihe ahụ n'ime akpa akọrọ, dị ọcha, kpuchie. Maka nnukwu ntapu: kpuchie ya na mpempe akwụkwọ plastik ma ọ bụ akwa akwa.
