ʻO ka hopena Sodium Bicarbonate: He ala i ka Sodium Hydrosulfide

ʻAʻohe wai sodium hydrosulfide

Hoʻomākaukau ʻia e like me ka mea i hōʻike ʻia ma luna nei ma lalo o nā kūlana paʻa ʻole o ka makū.

Wai NaHS Solution

Hoʻoheheʻe ʻia ka Sodium sulfide nonahydrate (Na₂S·9H₂O) i loko o ka wai i hoʻoheheʻe hou ʻia e hana i kahi 13% (w/v) ka hopena Na₂S.

Ma lalo o ka hoʻoulu ʻana a ma lalo 20°C, 14 g NaHCO₃ ua hoʻohui ʻia i 100 mL o kēia hopena, e hoʻoheheʻe koke ʻia ai a me ka hopena exothermic.

A laila hoʻohui ʻia he 100 mL methanol (e mālama ana i ka mahana

Ma hope o 10 mau minuke, kānana ʻia ka hui ʻana, a holoi ʻia ke koena me 50 mL methanol.

Aia i loko o ka kānana he ≥9 g NaHS a me ≤0.6 g Na₂CO₃ (~3.5 g NaHS a me 0.2 g Na₂CO₃ no 100 mL).

ʻO ka mea hoʻokuʻu aku i ka lama sodium hydrosulfide, loaʻa ka ʻikepili, kaomi ma aneʻi e kiʻi i nā laʻana manuahi.
