Sodium Haidrosulfaid feemɔ kɛtsɔ Sodium Ethoxide kɛ H2S nɔ
Hesaamɔ kɛtsɔ Sodium Ethoxide kɛ Hydrogen Sulfide ni Egbi nɔ
Nibii ahe gbɛjianɔtoo:
Akɛ 150 mL flask ni yɔɔ sɛɛgbɛ lɛ woɔ mli 20 mL ni ajie lɛ kpo ehee Ethanol ni nu bɛ mli kɛ 2 g ni ji sodium dade bibii ni he tse (ni oksaid bɛ mli).
Akɛ reflux condenser kɛ tsɔne ko ni haa nu lɛ mli fũuɔ lɛ woɔ flask lɛ mli, ni akɛ sɛɛgbɛ nine lɛ tsiɔ naa be kukuoo ko.
Beni sodium ethoxide lɛ jeɔ shishi efeɔ sɛɛ lɛ, nɔ kroko fataa he 40 mL ni ji ethanol ni nu bɛ mli akɛfataa he yɛ fãi amli kɛyashiɔ be mli ni efiteɔ kwraa.
Hetoo kɛ H2S ni egbi:
Akɛ glase tsɔne ko woɔ sidearm lɛ mli kɛtsɔɔ tsɔne lɛ mli, ni akɛ H2S gas ni egbi lɛ shwieɔ mli (kwɛ koni kɔɔyɔɔ akabote mli koni kɔɔyɔɔ akabote mli).
Akɛ H2S woɔ nu lɛ mli, ni no sɛɛ lɛ, ajieɔ nu ni shwieɔ shi lɛ fɛɛ kɛjɛɔ mli.
Akɛ nu ni mli tse lɛ woɔ conical flask ni egbi mli, ni... 50 mL ni ji ether ni yeɔ emuu lɛ fataa he, ni ehaa NaHS yɛŋ lɛ shwieɔ shi amrɔ nɔŋŋ.
Akɛ ether kroko (~110 mL fɛɛ) fataa he yɛ fãi amli kɛyashi nugbɔshiimɔ kroko baaa.
Akɛ nu ni hoɔ lɛ shwieɔ shi oya, ni akɛ absolute ether tsuɔ he nii shii 2–3, ni agbiɔ yɛ vacuum shishi.
Nɔ ni jɛɔ mli baa lɛ ji analytical hetsemɔ. Kɛha hetsemɔ ni nɔ kwɔ lɛ, abaanyɛ afee kristalo ekoŋŋ kɛjɛ ethanol/ether mli.
