He aha mea he anakahi i loko o kemika: ka ho'ākāka 'ana, examples, rula

Mea mea hoʻomau ana ma ka 'epekema paha e hoihoi i loko o kemika, e e hoihoi i ka ike i keia anakahi. Me keia manaʻo, he nui pilikia i loko o kemika papa, akā, kula kumu i ole haawi exhaustive ho'ākāka ma luna o ka loina o ka hana ana o ia waiwai. Pela ka mea he anakahi? No ke aha la LEDs hoʻololi i ke kala i loko o nā pāʻoihana? He aha nō pili? About kēia hope i loko o ka pauku.

ka wehewehena

Reference pane i ka nīnau mea ke anakahi, ke kēia ho'ākāka 'ana: he anakahi - IeAUPIIe, IAa IO ke aloha Nine Inch hui i ua hoʻohana' ia ka hoʻoholo 'ana i nā mea kiko'î o ka pāʻoihana (hydrogen ion lehulehu, ka equivalence wahi, i maopopo ai i ke alo o oxidants). Ma ka puali ano o ka olelo anakahi, e ike i ka waiwai, a e leie aku e hooholo i ka pH o ka meakino.

rula o ka hana

maopopo i ka maikaʻi aʻe ka mea malamalama, noonoo i ka loina o ka hana. Me lakou i mea hoike, lawe i ka metoʻalani. Kēia anakahi He He palupaluʻakika, a me kona mau haʻilula ka HR. Kēiaʻakika mea i loko o koʻana koko pāʻoihana dissociates i Ion H ⁺ a me R ^-. H ⁺ Ion i kaʻulaʻula kala like 'ole, R ^- - yellow, no ka mea, i loko o ka'ākilikai nā pāʻoihana (pH = 7) ka alani alakai. Inā ka hydrogen Ion mea oi aku ma mua o R ^-, ka pāʻoihana i ulaula (<7 pH), a me ka melemele ina Ion predominate R ^-. Nā hoailona paha e nāʻakika a me ka paʻakai a me kumu. Lākou mau rula o ka hana ua ka nānā 'ana ma luna o ka mea iniiaiie a me nā haumāna electrolytic dissociation.

Ke kiʻi ma lalo e hōʻike mai ana i ke ano o ka meto alani like me ka hana o ka hydrogen inideka. Ua ki i hōʻike i kēia anakahi ma ka kemika a me ka mea o kona manao.

examples o nā hoailona

Ka loa, he pono ole nā hoailona, i mea i loko o kēlā me kēia kula i ka litmus a me ka phenolphthalein. Litmus maʻakika,'ākilikai a'ākilikai meakino mai he okoa kala like 'ole, i hiki ole ke pioloke. Pepa holehole mai ai i impregnated me litmus pepa ua waiho ma ka pāʻoihana me kā lākou mau waihoʻoluʻu loli.

Phenolphtalein lawe i ke kala wale nō i loko o ka'ākilikai meakino, a lilo ulaula. Ua pili kekahi i loaʻa anakahi metoʻalani.

Ma lalo o keʻena hoʻokolohua kumu, a hiki ispolzovatsja emi na nā hoailona: metilviolet, meto ula, tenolftalein. e hoʻohana 'ia ka hapanui o nā hoailona wale nō i loko o kekahi wahi paiki pH huahelu, akā, ua paʻa nā hoailona, me losing i ka waiwai no kekahi aiee o ka hydrogen inideka.
