ʻO nā kaulike mālama ʻekolu no sodium hydrosulfide Nā Hoʻonā
Ma ke ʻano o ka mālama ʻana i ka nuipa i loko o nā hopena sodium hydrosulfide, ma muli o nā loina kemika a me nā wehewehe palapala, aia kahi pilina kūlike kikoʻī ma waena o nā mea sodium a me ka sulfur:
\(c(\kikokikona{Na}^+) = c(\kikokikona{HS}^-) + c(\kikokikona{S}^{2-}) + c(\kikokikona{H}_2\kikokikona{S})\)
Ua loaʻa kēia lakio mai ke ʻano kemika o ka sodium hydrosulfide (\(\text{NaHS}\)), e hōʻoia ana e mālama ka nui o ka sulfur ma kona mau ʻano āpau i kahi ʻāpana paʻa me ka nui o ka sodium.
No ka mālama ʻana i ka uku, e like me ke kumumanaʻo o ka electroneutrality i loko o nā hopena electrolyte (e like me ka mea i hōʻike kikoʻī ʻia ma nā puke aʻo kemika maʻamau), ʻo ka uku maikaʻi holoʻokoʻa i lawe ʻia e nā cations i loko o ka hopena e like me ka uku maikaʻi ʻole holoʻokoʻa i lawe ʻia e nā anions:
ʻO ka huaʻōlelo "c(\text{Na}^+) + c(\text{H}^+) = c(\text{HS}^-) + 2c(\text{S}^{2-}) + c(\text{OH}^-)\)
Hōʻike pololei kēia kaulike i ke kūlana kaulike o nā uku ionic i loko o ka hopena. E pili ana i ka mālama ʻana o ka proton, e like me ka mea i wehewehe ʻia ma nā pepa hoʻonaʻauao pili i ke kumumanaʻo acid-base, aia kahi pilina kikoʻī ma waena o nā ʻano o nā ion hydrogen a me nā ion hydroxide i hana ʻia e ka autoionization wai:
\(c(\kikokikona{OH}^-) = c(\kikokikona{H}^+) + c(\kikokikona{H}_2\kikokikona{S}) - c(\kikokikona{S}^{2-})\)
Hōʻike maopopo kēia i nā kaʻina hana hoʻoili proton e hana nei i loko o ka hopena.

ʻO kāu mea pono ʻoihana hilinaʻi i hoʻokumu ʻia i ka sulfur! Loaʻa i loko o 70% flakes, 30% solution me ka maʻemaʻe kiʻekiʻe, haʻahaʻa nā haumia, a me ka hana paʻa. Kūpono no ka wehe ʻana i ka lauoho ʻili a me ka tanning, ka flotation ore keleawe, ka kraft pulping, ka hoʻemi ʻana i ka dyeing textile, ka synthesis organik, a me ka wehe ʻana i ka metala kaumaha o ka wai ʻino. QC koʻikoʻi, ka maikaʻi o ka batch kūlike, ka hoʻopili maʻalahi, a me ka lako paʻa—hilinaʻi ʻia e nā mea kūʻai ʻoihana honua.info@anhaochemical.com
