'O ka moʻolelo ke kuleana o kahi mea e hoʻemi ai i ka wai a iʻole nā ​​kala ʻē aʻe. Hiki ke hoʻokahe a maikaʻi nā wai a me nā wai ʻaʻa wai i ka wai. Ma ka hoʻoheheʻe ʻia, māhele ʻia nā mea a pau i ʻekolu mau pūʻulu:

• molowa nui
• hoʻokaʻawale iki
• molowa

ʻAʻole i loaʻa nā mea kūpono ʻole, no laila he conditional inoa ka inoa a pono ʻoe e heluhelu "hoʻomaʻamaʻa hoʻomaʻamaʻa ʻole".

Pili loa ka hopena o nā mea ukali i ka mahana a me ke kaomi, no ka laʻana, ʻo ka KNO₃ (pākūkū nitrat) i ka mahana o + 20 ° C he solubility o 31.6 g / 100 g o ka wai, a ma ke ʻano o + 100 ° C - 245 g / 100 g o ka wai.

Mālama, hoʻohuihui a me ka hoʻolielene ʻia o nā paʻakai ma lalo o nā kūlana maʻamau

ʻO ka wehewehe no ka papa.

• P - hoʻoheheʻe ʻia ka paʻakai (ma mua o 0.1 mol / l),
• M - ka paʻū paʻolima wai (0.1-0.001 mol / l),
• N - paʻō paʻakai (emi mai ka 0.001 mol / l),
• [N] - Kaomi hoʻokolohua, ʻaʻole ho ,i ka paʻakai mai ka hopena, hoʻomoe ka paʻakai nui me ka hoʻokuʻu ʻana o ke kahe hau, Cr₂S₃ - ka hoʻokaumaha Cr (OH)₃ me ka hoʻokuʻu ana o ka hydrogen sulfide,
• + - paʻa i ka paʻakai me ka wai,
• - - ʻaʻole i kū,
• * P - hoʻonui ʻia e cation,
• P * - ka liuliu byia e ke anion.

Ka hoʻomau o nā paʻakai

ʻO nā wehewehe no ka papa

• 1 - paʻakai ka paʻakai i ka wai.
• 2 - kāpae liʻiliʻi i ka wai,
• 3 - kāpae ʻole i ka wai, akā hoʻōla ʻia i ka waʻaila a me nā minela o ke kō
• 4 - kāpīwī i ka wai a me ka waikawa kūloe, akā hoʻopōmaikaʻi i nā waikawa mineral,
• 5 - ʻaʻole paʻele ka paʻakai i ka wai, ʻaʻole hoʻi ma nā waikawa;
• 6 - hydrolyzed.

Inā makemake ʻoe i ka pūnaewele, e hoʻomaikaʻi nō mākou no kona kaila. ʻO kā mākou ʻāpana:
