Iyini Isixazululo Esigcwele?
Isixazululo siyingxube efanayo equkethe izinto ezimbili noma ngaphezulu. Into encibilikayo ibizwa ngokuthi i-solute, kanti into encibilikayo ibizwa ngokuthi i-solvent. Umqondo owodwa obalulekile kumakhemikhali wesisombululo yisisombululo esigcwalisiwe. Kulesi sihloko, sizoxoxa ngokujulile ngokuthi iyini isixazululo esigcwalisiwe, ukuthi sakha kanjani, izici zaso, kanye nokusetshenziswa kwaso ekuphileni kwansuku zonke.
Incazelo yesisombululo esigcwalisiwe
Isixazululo esigcwele yisisombululo esifinyelele ukulingana phakathi kwezinqubo zokuncibilika kanye nezokuna kwemvula. Ngamanye amazwi, esixazululweni esigcwele, inani le-solute lifinyelela inani eliphakeme kakhulu i-solvent engancibilika kulo ekushiseni okunikeziwe. Uma sifaka i-solute eyengeziwe esixazululweni esigcwele, ngeke incibilike futhi izohlala phansi kwesitsha.
Inqubo Yokwakhiwa Kwesixazululo Esigcwele
Inqubo yokwenza isixazululo esigcwele ingachazwa ngezigaba eziningana:
1. Ukuncibilika Kokuqala: Lapho i-solute ifakwa okokuqala ku-solvent, ama-molecule a-solute azoqala ukusebenzisana nama-molecule a-solvent. Lawa ma-molecule a-solute azosatshalaliswa ngokulinganayo kulo lonke i-solvent, akhe isixazululo esingagcwalisiwe.
2. Ukulingana Okuguquguqukayo: Njengoba i-solute ingezwa, isixazululo sisondela ekugcwaleni. Endaweni yokugcwala, kwenzeka ukulingana okuguquguqukayo phakathi kwenani le-solute elincibilikayo nalelo elithelayo. Kuleli qophelo, izinga lokuncibilika kwe-solute lilingana nezinga lemvula.
3. Izinga Lokushisa Nokucindezela: Izinga Lokushisa Nokucindezela kuthinta kakhulu ukuncibilika kwento ku-solvent. Isibonelo, ukuncibilika kukasawoti emanzini kuvame ukwanda ngokushisa okwandayo. Ngakho-ke, isixazululo esigcwele emazingeni okushisa aphansi singase singagcwali njengoba izinga lokushisa likhuphuka, njengoba amandla e-solvent okuncibilikisa into ekhuphukayo.
Izici zesisombululo esigcwalisiwe
Izixazululo ezigcwele zinezici eziningana ezizihlukanisa nezinye izinhlobo zezixazululo:
1. Ukuhlushwa Okuqhubekayo: Esixazululweni esigcwele, ukuhlushwa kwe-solute akushintshi uma izinga lokushisa kanye nokucindezela kuhlala kungaguquki. Lokhu kuphambene nesixazululo esingagcwali lapho ukuhlushwa kwe-solute kungashintsha ngokungeza i-solute eyengeziwe.
2. Ukulingana Okuguquguqukayo: Isixazululo esigcwele sisesimweni sokulingana okuguquguqukayo lapho inani le-solute elingena ku-solvent lilingana nenani eliphumayo.
3. Ukuna: Uma i-solute eyengeziwe ingezwa esixazululweni esigcwele, izonakala ngoba isixazululo asikwazi ukuncibilikisa i-solute eyengeziwe ngaphansi kwezimo ezinikeziwe.
4. Izinga Lokushisa Nokuncibilika: Ukuncibilika kuthonywa kakhulu izinga lokushisa. Isibonelo, ushukela uncibilika kalula emanzini ashisayo kunamanzi abandayo, ngakho-ke isixazululo esigcwaliswe kwelinye izinga lokushisa singase singagcwali kwelinye.
Ukusetshenziswa Kwezixazululo Ezigcwele Empilweni Yansuku Zonke
Izixazululo ezigcwele zinezinhlelo eziningi ezisebenzayo esingase singazazi ngokugcwele.
1. Ukwakheka Kwekristalu: Enye yezindlela ezibalulekile zokusebenzisa izixazululo ezigcwele ukwakheka kwekristalu. Ezimbonini eziningi, njengezimboni zikashukela, usawoti, kanye nezokwelapha, izixazululo ezigcwele zisetshenziselwa ukukhiqiza amakristalu anobukhulu obuthile kanye nezimo. Isibonelo, ushukela wekristalu embonini yokudla uvame ukukhiqizwa ngezixazululo zikashukela ezigcwele.
2. Ukwelashwa Kwemfucuza: Ekuphathweni kwemfucuza, izixazululo ezigcwele zingasetshenziswa ukwenza izinto ezinobuthi zibe yikristalu futhi zisuselwe esixazululweni ukuze zihlukaniswe futhi zilahlwe ngokuphephile.
3. Ukuna kweKhemikhali: Embonini yamakhemikhali, izixazululo ezigcwele zisetshenziselwa ukusheshisa amakhemikhali avela esixazululweni sawo. Lokhu kuvame ukusetshenziswa ezinqubweni zokuhlanza nokukhiqiza amakhemikhali athile.
4. Ibhalansi ye-Electrolyte Emzimbeni: Ku-biology, izixazululo ezigcwele zidlala indima ebalulekile ekugcineni ibhalansi ye-electrolyte kanye ne-osmosis yamaseli. Isibonelo, ibhalansi yama-ion e-sodium ne-potassium emzimbeni womuntu ibalulekile ekusebenzeni okuvamile kwamaseli.
5. Ukukhiqizwa Kwemikhiqizo Yezemithi: Imboni yezemithi ivame ukusebenzisa izixazululo ezigcwele enqubweni yokukhiqiza amaphilisi nama-capsule, lapho izithako ezisebenzayo kumele zixutshwe esixazululweni zibe sesimweni esigcwele ukuqinisekisa umthamo ofanele.
Ukuhlolwa Kwesixazululo Esigcwele
Kunezindlela eziningana ezingasetshenziswa ukuhlola ukuthi ikhambi ligcwele noma cha:
1. Ukwengeza i-Solute: Indlela elula ukwengeza inani elincane le-solute esixazululweni bese ubona ukuthi iyancibilika noma iyancibilika. Uma incibilika, isixazululo siyagcwala.
2. Ukulinganiswa Kokuncibilika: Ukuncibilika yinani eliphezulu le-solute elingancibilika ku-solvent ekushiseni okunikeziwe. Ngokulinganisa ukuhlushwa kwe-solute bese siqhathanisa nenani lokuncibilika, singanquma ukuthi isixazululo sigcwele noma cha.
3. Ukuhlolwa Kokuqhutshwa Komoya: Kwezinye izimo, ukuqhutshwa komoya kwesisombululo kungasetshenziswa ukuhlola ukugcwala. Kodwa-ke, le ndlela ifaneleka kakhulu kwizixazululo ze-electrolyte lapho ama-ion ancibilikisiwe enomthelela omkhulu ekuqhutshweni komoya kagesi.
Izici Ezithinta Ukuncibilika Kwezingxube
Ezinye izici ezithinta ukuncibilika kwe-solute ku-solvent zifaka:
1. Izinga Lokushisa: Ukwanda kwezinga lokushisa ngokuvamile kwandisa ukuncibilika kwezinto eziqinile kanye noketshezi ku-solvent. Kodwa-ke, kumagesi, ukwanda kwezinga lokushisa kuvame ukunciphisa ukuncibilika.
2. Ukucindezela: Ukucindezela kunethonya elikhulu ekuncibilikeni kwamagesi koketshezi. Ukucindezela okwandayo kuzokwandisa ukuncibilika kwamagesi.
3. Izakhiwo Zamakhemikhali: Izakhiwo zamakhemikhali ze-solute kanye ne-solvent nazo zithinta ukuncibilika. Amanye amakhemikhali ancibilika kakhulu ezinyibilikisini ze-polar, njengamanzi, kanti amanye ancibilika kakhulu ezinyibilikisini ezingezona ze-polar, njengamafutha.
4. Ukuba khona Kwamanye Ama-Ion: Kwezinye izimo, ukuba khona kwama-ion athile esixazululweni kungathinta ukuncibilika kwe-solute ngokusebenzisana kwama-ionic.
5. i-pH: Ezinye izinto ezincibilikayo zincibilikayo ezincike ku-pH yesisombululo. Isibonelo, ukuncibilika kwezinye izinto ezincibilikayo kungashintsha ngokushintsha kwe-pH.
Isiphetho
Izixazululo ezigcwele zidlala indima ebalulekile ezinhlobonhlobo zezicelo, kusukela embonini yokudla kanye nokwelashwa kwamanzi amdaka kuya kwezemithi kanye ne-biology. Ukuqonda umqondo wezixazululo ezigcwele, kanye nezici ezithonya ukuncibilika, kusenza sikwazi ukulawula nokusebenzisa izinqubo zamakhemikhali nezomzimba ekuphileni kwethu kwansuku zonke. Ngalolu lwazi, singenza izinqumo ezingcono ezicini ezahlukene, kusukela ekukhiqizweni kwezimboni kuya empilweni yomuntu siqu.
