Kaʻa Soda
ʻO ka caustic soda kahi keʻokeʻo keʻokeʻo me ka hygroscopicity ikaika. E hoʻoheheʻe ia a kahe ma hope o ka omo ʻana i ka waiū. Hiki iā ia ke omo i ka wai a me carbon dioxide i ka lewa e hana i ka sodium carbonate. He palupalu ia, hiki ke hoʻoheheʻe ʻia i ka wai, ʻalekohola, glycerin, akā ʻaʻole hiki ke hoʻoheheʻe ʻia i ka acetone. Hoʻokuʻu ʻia ka nui o ka wela ke hoʻoheheʻe. He paheʻe a alkaline ka hopena wai. He corrosive nui ia a hiki ke wela i ka ʻili a luku hoʻi i ka ʻaʻa fibrous. Hoʻopili me ka alumini i nā mahana kiʻekiʻe e hana i ka hydrogen. Hiki iā ia ke pale me nā waikawa a hana i nā ʻano paʻakai like ʻole. ʻO ka wai paʻakai hydroxide (ʻo ia hoʻi, alkali hiki ke hoʻoheheʻe ʻia) he wai poni-polū me kahi kopa a me ka paheʻe, a ʻo kona mau waiwai e like me ka alkali paʻa.
ʻO ka hoʻomākaukau o ka soda caustic he electrolytic a i ʻole kemika. ʻO nā hana kemika me ka lime causticization a i ʻole ferrit.
Hoʻohana nui ʻia ka hoʻohana ʻana i ka soda caustic i nā mea holoi synthetic, nā kopa, nā pepa pepa; hoʻohana pū ʻia me ka mea hoʻoheheʻe no nā kala wai kala a me nā kala nitrogen insoluble; hoʻohana pū ʻia i ka hana ʻana o ka ʻaila, nā olonā kemika, a me ka rayon; hoʻohana pū ʻia i ka lāʻau, e like me ka hana ʻana o ka wikamina C Wait. Hiki ke hoʻohana ʻia i ka synthetic synthetic a me nā ʻaila ʻaila a hoʻohana pololei ʻia ma ke ʻano he desiccant.
