Gal’vanik element tayyorlash.
Ikkita stakan olib, ularning 3-4 xajmigacha birinchisiga 1 M CuSO₄ eritmasidan, ikkinchisiga 1 M ZnSO₄ eritmasidan quying, so’ngra SuSO₄ eritmasiga mis plastinkasini, ZnSO₄ eritmasiga esa rux plastinkasini tushiring. Metall plastinkalarini sim bilan gal’vanometrga ulang. Nima kuzatiladi?
Eritmalarni elektrolit ko’prikchasi bilan tutashtiring, gal’vanometr strelkasini og’ishini kuzating. Elektr tok xosil bo’lishini tushuntiring va elektronlarning tashki zanjir bo’yicha yo’nalishini ko’rsating. YAsalgan gal’vanik elementning sxemasini tuzing va EYUK ni xisoblang.
