Sodium Hydrosulfide sɔrɔli NaOH tali fɛ
NaOH minɛcogo kɔrɔlen
Ni NaHS sodium hydrosulfide hakɛ sera 70% ye ., a bɛ dihydrate flakes dilan.
Ni a hakɛ ka dɔgɔn, a bɛ sɔrɔ i n’a fɔ trihydrate jilama.
Taabolo:
1 L 1 L kɔ saba bɛ kɛ ni fɛn ye min bɛ kɛ ni sɔgɔsɔgɔninjɛ ni kɔseginkɛlan ye (a sirilen bɛ CaCl2 jalen tubabukan na).
A bɛ fiyɛlilan saniya ni azote jalen ye, o kɔ, a bɛ charge ni Etanɔli jilama mililitiri 200 (3,4 mol)..
Sodiyɔmu nɛgɛ sanuman garamu 12 (0,522 mol) bɛ fara a kan yɔrɔ misɛnninw na ni a bɛ wuli ka segin a kan fo ka a wuli pewu.
Gazi dondaw bɛ don ji la, ka H2S jalen (min jalen don P2O5 kan) bɛ bugun ni bugun 5–10 ye sekɔndi kɔnɔ fo lɛri 2 ni a wulilen don.
Nɛnɛ kɔfɛ, etɛri jilama mililitiri 750 bɛ fara a kan walasa ka NaHS sodium hydrosulfide ja pewu.
