Pehea e ulu ai i nā kristal mai ka pa'akai a me nā mea'ē a'e?

Ma ka hale ho'ona'auao o ke kula a ma ka home e hiki iā'oe ke loa'a i nā kelikaliki nani a me nā pua o nā kulu li'ili'i, e uhi iā lākou me nā mea like'ole (nā pepa kope, nā huahelu o nā pae, pepa). Pehea e ulu nā pōaka o ka paakai mea hoʻoheheʻe i ka wai? Mai nā mea a pau e makemake e mālama i kēia'ike kūlana, e mālama'ia ka mālama, ka nānā a me ka ho'okō pololei'ana o ke a'o.

He aha ka crystallization?

Ke ho'ohemo'ia ka wai i ka wai, e komo ana nā mea komo i loko o ka hopena. 'O ka mea i kapa'ia he "crystallization". Ho'opili'ia kēia ka'ina me kahi loli o ka solubility o ka waiwai ma nā'ano like'ole. Me ka mālie mālie, ua waiho nā kilo i ka ho'opiha piha. I loko o ke'ano,'o nā huapili huahana e like me nā cubes, ho'opi'i'ia me nā'ao'ao'oi,'oi, pololei a me nā'ao'ao ma'ema'e. Pono no ka hoʻokolohua kekahi mau hui: paʻakai koloriside, kōpaʻa, potasiuma dichromate, ke keleawe sulphate a me nā waiwai. Hā'awi lākou i nā leo kala o nā'ano like'ole a me nā lau. 'O ka mea ma'alahi o nā pūpū wai'ia ka sodium chloride. He palekana ka waiwai no nā kānaka,'a'ole ia e alaka'i i ke ahi ke loa'a i ka'ili a i loko o ke kino. E'ike i kahi pehea e ulu koke ai i nā kānana pa'akai.

Kōkua kōkua

I ka hana'ana i ka ho'okolohua, pono'oe e hahai i nā leka ma'alahi. Hiki i kēia ke ho'onā i ka manawa pōkole e loa'a i nā'ele'ele ma'amau ma'amau:

• ke hoʻohana demineralised paha i puhi ia i ka wai ;
• No ka ulu'ana i nā kalikena o nā mea me ka palaka maika'i;
• E ho'omohala i nā hana ma nā kī'aha ma'ema'e;
• E ho'opili i ka hopena (hiki iā'oe ke ho'ohana i kahi kāwele pepa).

Hiki iā'oe ke nānā i ke ka'ina hana, akā'a'ole e ho'oluliluli a ho'one'e i ka pahu. Nui nā po'e i ka pehea e ulu ai i nā kristal mai ka pa'akai ke'ano o ka nui. 'O nā mea a pau e pili ana i ka mahana kahi e loa'a ai ka hopena piha, a ma ke alo ho'i o nā mea'ele'ele a me nā mea haumia.

Me ka mālie ha'aha'a, hā'ule nā kristel nui, a'o ka wikiwiki, hā'ule ka nui o nā kristal a me nā li'ili'i li'ili'i. E ho'omaha i ka pahu me ka hopena i waiho'ia i loko o kahi lumi anuanu ai'ole e ho'okomo'ia i loko o ke pola me ka wai a me nā'āpana hau.

He aha nā mea e pono ai no ka'ike?

'O ka papahana ho'olālā "Nā pa'akikī pa'akai e ulu ana" hiki ke hana maika'i'ia ma ka home. Pono nā mea a me nā mea li'ili'i loa:

• Ke'ōmole'ōmole a i'ole ke aniani (hiki iā'oe ke lawe i kahi ipu);
• 'O kahi pā no ka ho'omaha'ana ma kahi wai holoi;
• He pola wai anuanu kahi e ho'oma'ama'a'ia ai kahi wai piha;
• E ku i ke kuhi (tioa a i'ole ka lā'au);
• ka funnel a me ka Kānana pepa (pepa pepa);
• 'O kahi thermometer no ka wai;
• keleawe uea, Clip;
• Kōkuhi;
• He lā'au mai ka'ulu cream ai'ole he penikala;
• Ka hapalua o ke kī'aha o ka pa'akai pa'akai;
• 'O ke kai me ke kai.

Pehea e hana ai i nā tiole mai ka pa'akai? Ke a'o a'o no ka hana'enehana

Ma mua, e koho i ka pa'akai nui loa mai nā kulika, a laila, lawelawe lākou i mau mea kanu. E ho'opa'a iā lākou i ke kaula, e ho'opili iā ia me kahi lā'au mai ka hau'ulu (penikala). 'Oiai e kau ana kēia i kahi hakahaka a ho'omākaukau i kahi ho'opiha piha. Pono'ia ka ho'ohana'ana i kahi mea puhi wela. E mālama iā'oe'a'ole e pīpī i ka wai wela, mai loa'a ka puhi mai ka mea puhi.

Ka hanana hana:

1. Hulu i ho'okahi teaspoon o ka pa'akai pa'akai i loko o ka pahu wai a kau ma kahi wai'au'au (90 ° C). E ho'omau i ke ho'oikaika i ka wai me kahi lā'au a hiki i ka wā e pau loa ai ka pa'akai.
2. E ho'omau i ka ho'ohui'ana i ke kino a hiki i ka wā e pau ai. E hele i ka helu ma 100 ° C i 100 ml o ka wai 39.2 g o ka sodium chloride.
3. Ke hiki i ke ku'i'ana, ho'opiha i ka ho'omehana. E ho'opili i ka wai wela i loko o kekahi pahu.
4. E ho'oku'u i ka filament me ka mea nui e ho'omaka ai i ke ka'ina hana.

Ma hope iho, e ulu ana ka pa'akai o ka pa'akai pa'akai. Pono e loa'a a malo'o ma kahi kāwele pepa. Hiki iā'oe ke hana i ka ho'okolohua me ka ho'omaka'ole'ana i ka crystallization a e ho'olei i kahi'āpana lili e pili i ka pae. Ma laila e ulu ana nā kristal. Inā'oe e uhi iā lākou me kahi'iliahi kīnā'ole, a laila e mālama pono'ia lākou.

Pehea e loa'a ai nā kulu'ele'ele uliuli?

Hiki ke ho'opili'ia ka sulfate sulfate i loko o ka wai. Mai kēia mea, hiki iā'oe ke ulu i nā pōhaku'ele'ele nui. Akā, pono e mālama pono i ka ho'okolohua - he mea'awa'awa ka pūpū. Pehea e ulu nā pōaka o ka paakai i mea he mea pōaka hydrate o ke keleawe sulufahate? Hiki ke ulu i nā mea nui a nani loa ma ke kau'ana i kahi'āpana ho'okomo i loko o ka hopena. No ka loa'a'ana, ua ninini'ia ka waihehe'e sulfate pāpa'a i'oi aku ka ha'aha'a i ka pīpī a ho'oku'u'ia i ka pō. 'O nā kristal pa'akikī i hā'ule i ka mea nui, ua kaula'i'ia i kahi kaula silk a ho'oha'aha'a'ia i loko o kahi pale i ho'omohana'ia i'ole e pā i nā paia a me ka lalo o ka pahu. I ka lewa, e pau ka wai pa'a i ke keleawe sulfate, e lilo ia i'ele'ele'ōma'oma'o malo'o he keleawe sulfate. Pono pono e ho'omalo'o i ka pōhaku aniani a me ka'ona.

Pehea e ulu ai i nā kristal mai ka pa'akai ma ke'ano o nā leka a me nā ki'i?

I nā'a'ale'a, e ho'omākaukau, e like me nā kuhikuhi, kahi ho'opiha piha o ka pa'akai, keleawe sulfate, sugar, potassium dichromate (ma nā moku like'ole). No nā mea ke'oke'o, hiki ke ho'ohana'ia nā'ono o nā mea'ai. E hana i kekahi kaula kelepona mai kahi ki'i ai'ole leka. E ho'opa'a iā ia me nā wulu ke'oke'o. E ho'one'e i nā pūpū i ho'omākaukau'ia ma luna o nā kānana i loko o nā kānana i'oi'ole ka mahana i'ole e pā i ka lepo a me nā paia o nā pū. I kahi lā a i'ole wikiwiki paha, e uhi'ia nā ki'i i nā tiole. E lawe iā lākou i waho, e ho'omalo'o ma kahi pepa'ūwele a e uhi'ia me ke kui kui'ole. He mau mana'o no ka ho'ohana'ana i nā momala ulu:

• Hō'ike i ke kula ma ke kumuhana "Solutions";
• Ka inoa o kahi hō'ike e pili ana i ke ka'ina hana o ka hale hana leka;
• 'O ka nani o ka nūpepa pepa pa'ipa'i;
• Ke hana 'ana i nā mea' uliuli no ka Mele Kalikimaka;
• Nā makana i nā hoaaloha, nā kumu, nā mākua;
• Ka ho'okumu'ana i kahi hō'ili'ili o nā kristal ulu.
