Indlela yokutyala ziikristale yetyuwa kunye nezinye izinto?

Elabhoratri esikolweni nasekhaya ungafumana ziikristale ezintle olunye okanye ezisebenzisanayo ziikristale ezincinane, bagqubuthele izinto ezahlukeneyo (umboniso paper, Ngemisonto, imifanekiso ephepheni). Indlela yokutyala ziikristale yetyuwa unyityilikiswa emanzini? Nakubani na onqwenela ukwenza oku amava umdla, kufuneka ukuchaneka, ingqalelo, nokubulawa echanekileyo imiyalelo.

Yintoni crystallization?

Xa ukunyibilikisa iyeza emanzini, amasuntswana baye isisombululo. Isenzeko reverse ubizwa ngokuba "crystallization". Le nkqubo ezinxulumene notshintsho ukunyibilika ukwimo kwiqondo lobushushu ezahlukeneyo. Kancane olupholisa i ziikristale kuwa ngaphandle umxube. Imilo ye amasuntswana onesiphumo ezifana neetyhubhu, iidayimani kunye elibukhali, elintlangothi ngqo kunye namacala egudileyo. Ifanelekile nokuhlola iikhompawundi ezahlukeneyo: chloride sodium, iswekile, potassium dichromate, sulphate ubhedu kunye nezinye izinto. Balirhola eyahlukileyo imilo kunye nombala kwakheka. Eyona ekhoyo yamanzi-enyibilikayo iikhompawundi - ityuwa. Le into Kukhuselekile abantu, loo nto ikhokelele ekubeni kunditshisa udibana nesikhumba okanye ngaphakathi emzimbeni. Makhe sibone indlela nkqi ukukhula zamagaqa etyuwa.

amacebo aluncedo

ngqo imithetho elula efunekayo xa esenza amava. Oku kuya kuvumela ukufumana ngokukhawuleza ziikristale ezinkulu semilo rhoqo:

• ukusebenzisa demineralised okanye amanzi Yek ;
• izinto ukuba ukukhula ziikristale ukuba ukunyibilika elungileyo;
• kokuchitha amava entweni ecocekileyo;
• isisombululo ecociweyo (ngokusebenzisa itawuli yephepha kunokwenzeka).

Le nkqubo ibonakala, kodwa ukugungqa ukuhambisa akufuneki ukuba isikhongozeli. Abantu abaninzi bayazibuza ukuba zikhule njani ziikristale yetyuwa, kangangokuba elimlinganiselo ethile. Konke kuxhomekeke lobushushu apho isisombululo isinyibiliko kwakhona ubukho kwamasuntswana undissolved kunye ukungcola.

Nge Ukupholisa kade ziikristale ezinkulu kuwa, yaye ngokukhawuleza - eninzi abaphakathi nabancinane. Ukupholisa ingqayi kunye isisombululo kusala kwigumbi ebandayo, okanye ibekwe isitya ngamanzi ice iityhubhu.

kufuneka ntoni izixhobo amava?

Lab "Ukulinywa ziikristale wetyuwa" inokwenziwa ekhaya ngempumelelo. Kungathatha izinto ilula kakhulu zingangeni:

• igutyana iglasi okanye kwitoti (ungathatha bank);
• pan ukufudumeza kwi bath kwamanzi;
• isitya ngamanzi abandayo, apho isisombululo ifumile lupholisiwe;
• coli for ukukhwezela (iglasi okanye imithi);
• Nefaneli kunye nephepha filter (itawuli yephepha);
• Sikali amanzi;
• ucingo lobhedu, clip;
• intambo;
• ice cream intonga okanye ipensile;
• ityuwa polstakana;
• amanzi demineralized.

Indlela ziikristale yetyuwa? Ukufundiswa bekusetyenzwa elebhu

Khetha kwangaphambili le ziikristale letyuwa, ukutya inkulu, baya kuba amasuntswana imbewu. Tie ukuba kumtya, ukuyiphotha unamathele ukusuka cream ice (ipensile). Nangona ukubeka le preform nokulungiselela umxube. Ifuna ukusetyenziswa nehitha. Qaphela ukuba ngakweli amanzi ashushu akuthethi ukuze itshiswe zisiza.

inkqubela:

1. Enye itispuni yetyuwa uthululele neselwa lamanzi kunye nendawo emanzini emanzini (90 ° C). Njalo ushukumisa wand ulwelo de zokuchithwa olupheleleyo neetyuwa izabelo.
2. Qhubeka ukuze ukongeza into ide iyachithakala. Ucinge ukuba kwi-100 ° C 100 ml yamanzi itshitshisiwe 39.2 g sodium chloride.
3. Xa Ukwanda sifikelelwayo, uzivalele phantsi ubushushu. Icebo lokucoca ulwelo eshushu kwezinye ebhankini.
4. Awuthi nkxu isisombululo sifudumele ukuba azinamsonto kunye kwisuntswana ukuqalisa inkqubo.

Emva kwexesha elithile yokutyala nomkhenkce yetyuwa. Kufuneka ukufumana ze uyigandele omile itawuli yephepha. Kuyenzeka ukuba enze ulingelo ngaphandle kokuqala i crystallization okanye umsonto esezantsi ebotshelelwe ikliphu metal. Iza kuya ikhula kwakheka. Ukuba kukugubungela nabo ivanishi, Bagciniwe ngcono.

Ungayifumana njani le crystals aluhlaza?

sulfate sobhedu enyibilikayo kakhulu emanzini. ziikristale ezinkulu blue zikhuliswa kule iziyobisi. Nje ke nikunyamekele ukuyigcina amava - inamehlo ityhefu. Indlela yokutyala ziikristale ye ityuwa nto leyo ukuphilisa crystalline of sulfate yobhedu? Uyakwazi ukhule iipateni ezinkulu, ezintle kakhulu, ukuba ufake ekusunguleni isisombululo. Ukuze ufumane oko esosini kuso isuntswana isisombululo supersaturated of sulfate yobhedu yokulala ngasekhohlo. Ukususela ziikristale abazahlulayo lukhethiwe lowo enkulu, ebotshelelwe ngomsonto isilika, kunye badl isisombululo eshushu befumile ukuze ungabinako bachukumise iindonga kunye nasezantsi embizeni. Xa uzibona sulfate yobhedu zamanzi ziba sibotshiweyo, luba baluthuthu zana sulfate powder zezobhedu. Kufuneka ube ukulungele ukuba zome nomkhenkce kunye lacquered.

Indlela yokutyala ziikristale letyuwa ngohlobo oonobumba namanani?

Xa iibhanki ukulungiselela ngokungqinelana anetyuwa uqeqesho, sulfate ubhedu, iswekile, potassium dichromate (omonakalo ibhotile). Izinto ezimhlophe Ungasebenzisa nedayi yokutya. Yenza umzobo wire obhityileyo okanye ileta. imisonto White yoboya azisongele ngenyameko oko. scaffolds Lower ilungiswe zokumiswa kwi kodwa zipholile izisombululo supersaturated ukuba ngaba akufiki ezantsi kwaye neendonga neenkonkxa. Iyeza imini okanye imifanekiso oluikhawuleza wambu kwakheka. Susa manzi emoyeni kwi itawuli yephepha baze ezingenambala iinzipho. A iingcamango ezimbalwa kuba crystals abadala:

• ntetho kwisikolo enomxholo othi "Solutions";
• Ingxelo design kwi ukuziphatha bekusetyenzwa elebhu;
• UMhombiso iphephandaba udonga festive;
• imveliso zokudlala ngeKrismesi imithi Christmas;
• izipho abahlobo, ootitshala, abazali;
• ngokudala uqokelelo crystals likhule.
