Magnesium Sulphate
He pūhui i loaʻa ka magnesium, he mea hoʻohana maʻamau a me ka mea hoʻomaloʻo, ʻo ia ka magnesium cation Mg2+ (20.19% ma ka nuipa) a me ka anion sulfate SO2−4.Paʻa keʻokeʻo keʻokeʻo, hiki ke hoʻoheheʻe ʻia i ka wai, hiki ʻole ke hoʻoheheʻe ʻia i ka ethanol.Loaʻa pinepine ʻia ma ke ʻano o ka hydrate MgSO4·nH2O, no nā helu n like ʻole ma waena o 1 a me 11. ʻO ka mea maʻamau ʻo MgSO4·7H2O.

Sodium Bisulfate
ʻO ka sodium bisulphate, ʻike ʻia hoʻi ʻo ka sodium acid sulfate, he sodium chloride (paʻakai) a hiki i ka sulfuric acid ke hana i nā wela kiʻekiʻe e hana i kahi mea, ʻo ka mea anhydrous he hygroscopic, aqueous solution he waikawa.He electrolyte ikaika ia, ua hoʻoheheʻe ʻia i loko o ke ʻano hoʻoheheʻe ʻia, i hoʻohui ʻia i loko o ka sodium a me ka bisulfate.Hiki i ka hydrogen sulfate ke ionization pono'ī wale nō, he liʻiliʻi loa ka ionization equilibrium mau, ʻaʻole hiki ke hoʻopau loa.

Ferrous Sulfate
ʻO ka ferrous sulfate he mea anorganic, ʻo ka crystalline hydrate he heptahydrate i ka mahana maʻamau, i kapa ʻia ʻo "'ōmaʻomaʻo alum", ʻōmaʻomaʻo ʻōmaʻomaʻo ʻōmaʻomaʻo, i hoʻoheheʻe ʻia i ka ea maloʻo, ʻo ka oxidation o ka ʻeleʻele iron sulfate i loko o ka ea humid, ma 56.6 ℃ e lilo tetrahydrate, ma 65 ℃ e lilo i monohydrate.Hiki ke hoʻoheheʻe ʻia ka ferrous sulfate i ka wai a aneane hiki ʻole ke hoʻoheheʻe ʻia i ka ethanol.Kona wai hoʻoheheʻe oxidize mālie i ka ea ke anu, a oxidizes wikiwiki i ka wa wela.ʻO ka hoʻohui ʻana i ka alkali a i ʻole ka ʻike ʻana i ka mālamalama hiki ke hoʻolalelale i kona oxidation.ʻO ka mānoanoa pili (d15) he 1.897.

Magnesium Chloride
He mea anoano i haku ʻia me 74.54% chlorine a me 25.48% magnesium a maʻamau i loko o ʻeono mau mole o ka wai kristal, MgCl2.6H2O.ʻO ke aniani monoclinic, a i ʻole ka paʻakai, loaʻa kekahi ʻano corrosive.Hoʻokumu ʻia ka Magnesium oxide ke nalowale ka wai a me ka hydrogen chloride i ka wā hoʻomehana.Hiki ke hoʻoheheʻe ʻia i ka acetone, hiki ke hoʻoheheʻe ʻia i ka wai, ethanol, methanol, pyridine.He deliqueses a hana i ka uahi i ka pulu ea, a sublimates ke keʻokeʻo wela i loko o ke kinoea kahawai o ka hydrogen.
