Unyango lweSodium Sulfide kunye neTitration:
I-Pipette 200 mL yeSolution B kwiflaski yevolumu engama-500 mL. Yongeza ngokulandelanayo i-40 mL yesisombululo se-sodium carbonate, i-80 mL yesisombululo se-zinc sulfate, kunye ne-25 mL ye-ethanol. Xuba amanzi uze udibanise kakuhle.
Hluza umxube, ulahle i-10 mL yokuqala ye-filtrate, uze ufake i-100 mL ye-filtrate kwi-flask ye-500 mL ekhonkrithi. I-Sodium Sulfide.
