lehu kopa

ʻO ka wehewehe pōkole:

ʻO ka lehu soda kekahi o nā mea kumu no ka ʻoihana kemika, hoʻohana nui ʻia no ka metallurgy, aniani, textile, dye paʻi, lāʻau lapaʻau, synthetic detergent, petroleum a me ka ʻoihana meaʻai etc.

1. Inoa: Soda lehu mānoanoa

2. Huina mole: Na2CO3

3. Kaumaha molekula: 106

4. Pono Kino: Astringent ono;ka mānoanoa pili o 2.532;helu hehee 851 °C;hiki ke hoʻoheheʻe 21g 20 °C.

5. Nā waiwai kemika: Paʻa ikaika, akā hiki ke decomposed i ka wela kiʻekiʻe e hana i ka sodium oxide a me carbon dioxide.ʻO ka hoʻoheheʻe ʻana i ka wai ikaika, maʻalahi ke hana i kahi puʻupuʻu, ʻaʻole decompose i nā mahana kiʻekiʻe.

6. Solubility: hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i ka ethanol, hiki ʻole ke hoʻoheheʻe ʻia i ka waiʻona.

7. Keʻano: ka pauka keʻokeʻo

E hoʻouna i ka leka uila iā mākou

1.ʻO ka hanaʻana i ke aniani kekahi o nā mea nui loa o ka sodium carbonate.Ke hoʻohui ʻia me ka silica (SiO2) a me ka calcium carbonate (CaCO3) a hoʻomehana ʻia i nā wela kiʻekiʻe loa, a laila hoʻomaloʻo wikiwiki loa, hana ʻia ke aniani.Ua kapa ʻia kēia ʻano aniani ʻo ke aniani soda lime.

2. Hoʻohana ʻia ka lehu soda e hoʻomaʻemaʻe i ka ea a hoʻomaʻemaʻe i ka wai.

3. Ka hana ʻana i ka Soda Caustic a me nā mea ʻala

4. metallurgy (ka hana ʻana i ke kila a me ka unuhi ʻana i ka hao etc.),

5. (ke aniani pālahalaha, ka ipu lepo maʻemaʻe)

6. ka pale aupuni (TNT manufacturing, 60% gelatin-type dynamite) a me kekahi mau mea e ae, e like me ka aila pohaku, ka hana pepa, ka pena, ka paakai hoomaemae, ka palupalu o ka wai paa, ke kopa, ka laau lapaau, ka ai a pela aku.
