SULFIDHO

SULFIDHO (az lotinisulphur, sulfur — sulfur), payvasthoi khimiyavii sulfur bo metallho va baze gayrimetallho; namakhoi kislotai gidrogensulfid (N₂S). Sulfidho du khel meshavand: Sulfidhoi miyona — M₂S va tursh (gidrosulfidho) — MNS (M — metalli yakvalenta).

Sulfidhoi metallhoi ishqori moddahoi berang buda, dar ob nagz hal meshavand. Muhiti mahluli obiashon ishqorist. Az tasiri kislotahoi serob N₂S judo mekunand.

Sulfidhoi metallhoi ishqorzamini niz moddahoi berang buda, dar ob bad hal meshavand. Dar havoi nam N₂S judo mekunand. Ham Sulfidhoi metallhoi ishqori va ham Sulfidhoi metallhoi ishqorzamini to sulfatho oksid meshavand.

Sulfidhoi metallhoi vaznin dar obhal nameshavand. Rangashon gunogun. Sulfidhoro bo rohhoi zerin hosil mekunand:

1) payvastshavii bevositai elementho; 2) tasiro mahlulhoi obii namakho bo N₂S yo (NN₄)₂S; 3) tasiri gidrooksidho bo N₂S; 4) bo rohi bo angisht barqaror namudani sulfatho.

Sulfidho dar sohahoi gunoguni khojagii khalq istifoda meshavand: dar istehsoli charm, khojagii qishloq, sanoati khimiya va gayra.
