Roobabka cas ayaa laga yaabaa inay noqdaan roobab polysulfide sodium ah.Sodium sulfide waxay u badan tahay in hawada lagu oxidized sodium polysulfide (ka samee baaruud hal arrin, ka dibna soo saara sodium polysulfide). Marka index sulfur ee sodium polysulfide uu sarreeyo, waa casaan mugdi ah oo ku jira xalalka aqueous, oo waxay soo baxdaa sababtoo ah xal aan la milmi karin oo ku jira xaaladaha anaqueous. Intaa waxaa dheer, tetrachloride carbon ayaa sidoo kale laga yaabaa inay u jajabiso sodium chloride (potassium) + sodium carbonate (potassium). iyo biyaha (1: 6 falcelinta waa la qori karaa).
Aqoonsiga habka tixraaca roobabka cas-cas
Ka saar walaxda cas oo dhowr jeer ku maydh ethanol dhammaystiran (isku day inaad maydho xalalka sodium sulfide) si aad u aragto inay milanto , oo dhowr jeer ku dhaq ethanol. Qaado qadar yar oo roob ah oo milo sulfuric acid, fiiri haddii ay jirto baxsashada hydrogen sulfide (waa inaad awood u leedahay inaad ursato, waxaad sidoo kale isticmaali kartaa acetate macdanta rasaasta qoyan ama baaritaanka warqadda tijaabada nitrate-ka) , Roobka haddii xaddi badan oo beddelka galay turbidity huruud iftiin ama caano ah, tani waa wax soo saarka ee sodium polysulfide (potassium) ifafaale. Tijaabooyinka kor ku xusan caddeeyey in sodium polysulfide (potassium) .Waxa kale oo loo qaabayn karaa si loo caddeeyo haddii ay jirto wax-soo-saarka kaarboon (carbon tetrachloride alkali badeecooyinka kala dunsan).
