Nā Waiwai o ka Sodium Sulfide
Kemika Formula: Na₂S
Kaumaha Molekala: 78.04
ʻAno a me ka Hoʻohuihui ʻana
He hygroscopic loa ka sodium sulfide. He maʻalahi ia e hoʻoheheʻe ʻia i ka wai, hoʻoheheʻe iki ʻia i ka ethanol, a ʻaʻole hoʻoheheʻe ʻia i ka ether. He alkaline ikaika kona hopena wai a hiki ke hoʻoulu i nā kuni ke hoʻopili ʻia me ka ʻili a i ʻole ka lauoho. No laila, ua ʻike nui ʻia ka sodium sulfide ʻo ia ka sulfide alkali. Hoʻomake maʻalahi ia i ka lewa a pane me nā waikawa ikaika e hoʻokuʻu i ke kinoea hydrogen sulfide. Hiki iā ia ke hana i nā precipitates metal sulfide insoluble ke pane ʻia me nā ʻano hopena paʻakai metala kaumaha like ʻole.

Loaʻa iā Sodium sulfide ka palapala hōʻoia ʻaoʻao ʻekolu SGS, palapala hōʻoia pae ʻoihana, a ua hala i ka palapala hōʻoia ʻōnaehana maikaʻi honua ISO a me ka palapala hōʻoia hoʻokō REACH. Kaomi ma aneʻi e kiʻi i kahi ʻōlelo hoʻēmi.
