Chitsanzo cha Redox Reactions Mafunso ndi Kukambirana Chiyambi cha Redox Reactions Redox (reduction-oxidation) reaction ndi chemical reaction momwe ma elekitironi amasamutsidwira pakati pa mitundu iwiri ya mankhwala. Reaction iyi imaphatikizapo kusintha kwa kuchuluka kwa okosijeni wa maatomu mkati mwa molekyulu, ayoni, kapena chophatikizika. Mawu oti "redox" amachokera ku malingaliro awiri: kuchepetsa ndi okosijeni. Kuchepetsa ndi njira yomwe chinthu... Werengani zambiri

Zitsanzo za mafunso okhudza Ma Electrolyte Olimba, Ma Electrolyte Ofooka, ndi Osakhala Ma Electrolyte. Ma Electrolyte ndi mfundo yofunikira mu chemistry yomwe ndi yofunika kwambiri, makamaka pophunzira za momwe zinthu zimakhudzira mayankho. Ma Electrolyte ndi mankhwala omwe, akasungunuka m'madzi, amapanga ma ayoni omwe amalola yankho kuyendetsa magetsi. Kutengera kuthekera kwawo kugawanika kukhala ma ayoni, ma electrolyte amagawidwa m'magulu atatu... Werengani zambiri

Chitsanzo cha Mafunso Okambirana a Electrolyte Ma Electrolyte ndi zinthu zomwe zimatha kuyendetsa magetsi zikasungunuka m'madzi kapena zinthu zina zosungunulira. Ma electrolyte amagawidwa m'magulu awiri akuluakulu: ma electrolyte amphamvu ndi ma electrolyte ofooka. Ma electrolyte amphamvu amasinthidwa kukhala ayoni kwathunthu mu yankho, pomwe ma electrolyte ofooka amasinthidwa kukhala ayoni pang'ono. Ma electrolyte amachita gawo lofunikira pazochitika zosiyanasiyana zamakemikolo ndi moyo watsiku ndi tsiku. Munkhaniyi… Werengani zambiri

Mafunso Okambirana za Electrochemistry: Electrochemistry ndi nthambi ya chemistry yomwe imaphunzira ubale pakati pa zochita za mankhwala ndi kusintha kwa mphamvu zamagetsi. Mu electrochemistry, pali mfundo zazikulu ziwiri: okosijeni (kutulutsidwa kwa ma elekitironi) ndi kuchepetsa (kuchuluka kwa ma elekitironi). Njirazi zitha kuwonedwa m'mitundu iwiri ya maselo a electrochemical: maselo a voltaic (maselo a galvanic) ndi maselo a electrolytic. Nazi zitsanzo za mafunso pamodzi ndi... Werengani zambiri

Mafunso ndi Zitsanzo za Momwe Mungapangire Colloids Colloids ndi zosakaniza zomwe tinthu ta gawo limodzi kapena angapo timagawidwa mofanana mu chogawaniza. Colloids imagwiritsidwa ntchito m'njira zosiyanasiyana pa moyo watsiku ndi tsiku, kuyambira chakudya ndi zodzoladzola mpaka mankhwala ndi mafakitale. Kuti timvetse bwino momwe tingapangire colloids, tiyeni tiyambe kukambirana mafunso ena... Werengani zambiri

Chitsanzo cha Mafunso Okambirana za Katundu wa Colloidal Colloids ndi mtundu wa chisakanizo chomwe chinthu chimodzi chimafalikira mofanana mu chinthu china.
