ʻO ka Sodium Metabisulphite Na2S2O5 No ka ʻOihana Kemika
ʻO ka sodium metabisulphite (Na2S2O5) he mea hoʻohuihui inorganic i ke ʻano o nā keʻokeʻo keʻokeʻo a melemele paha me kahi ʻala ʻala ikaika. Hiki ke hoʻoheheʻe ʻia i loko o ka wai, ʻakika kona ʻano wai. Ma ka hui ʻana me nā ʻakika ikaika, hoʻokuʻu ka sodium metabisulphite i ka sulfur dioxide a hana i ka paʻakai pili. Eia naʻe, pono e hoʻomaopopo ʻia ʻaʻole kūpono kēia pūhui no ka mālama ʻana i ka wā lōʻihi, no ka mea, e hoʻoneʻe ʻia ia i ka sodium sulfate ke ʻike ʻia i ka ea.
