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 maydh ethanol. Qaado qadar yar oo roob ah oo qas sulfuric acid, arag haddii ay jirto baxsashada hydrogen sulfide (waa inaad awood u leedahay inaad ursato, sidoo kale waxaad isticmaali kartaa Acetate sunta rasaasta qoyan ama baaritaanka warqadda nitrate-ka rasaasta rasaasta), roobabka haddii ay tahay qadar badan oo beddelaad ah oo isu beddelaya turbidity huruud fudud ama caano leh, tani waa wax soo saarka sodium polysulfide (potassium) ifafaale. Tijaabooyinka kor ku xusan waxay caddeeyeen in sodium polysulfide (potassium). Waxa kale oo loo qaabayn karaa si loo caddeeyo in uu jiro wax soo saarka karboonaydh (carbon tetrachloride alkali decomposition product) iyo in kale.
