8- Nazorat ishi
Nazorat ishi o’tkazilgan sana _____________ Mavzu:Elektroliz. Nazorat shakli:Yozma ish. I-variant. AgNO3 eritmasi orqali 5 amper tok 13,4 soat mobaynida o’tkazilganda katodda hosil bo’lgan metallni massasini toping? 52 gr Cd SO4 ni elektroliz qilish 6 amper tok qancha vaqt (sekund) mobaynida o’tkazilishi kerak? 1500 g 8 % CuSO4 ning eritmasi elektroliz qilinganda anodda (inert elektrod) 30,8 l (n.sh.) gaz ajraldi. Elektrolizdan so’ng hosil bo’lgan moddaning massa ulushini (%) hisoblang. 400 ml 0,2 M li eritma tayyorlash uchun soda kristallgidratidan necha g olish kerak Kompetentlikni aniqlash uchun materiallar: 5.Doimiy ravishda iste’mol qiladigan osh tuzimizni eritmasini elektroliz qilganimizda katodda va anodda qanday moddalar ajralib chiqadi?(reaksiya tenglamasini yozing.) II-variant 1.4 mol vodorоd pеrоksidi pоrtlаsh uchun 3А to’liq qаnchа vаqt dаvоmidа o’tkаzilishi kеrаk? 2.CuSO4 eritmasi orqali 2 amper tok 193 cekuntd mobaynida o’tkazilganda katodda hosil bo’lgan metall massasini toping? 3. 500 g 8 % CuSO4 ning eritmasi elektroliz qilinganda anodda (inert elektrod) 22,4 l (n.sh.) gaz ajraldi. Elektrolizdan so’ng hosil bo’lgan moddaning massa ulushini (%) hisoblang. 4. 2 litr 2 molyar eritma tayyorlash uchun qancha mol kaliy gidroksid kerak? Kompetentlikni aniqlash uchun materiallar: 5. Doimiy ravishda iste’mol qiladigan osh tuzimizni eritmasini elektroliz qilganimizda katodda va anodda qanday moddalar ajralib chiqadi?(reaksiya tenglamasini yozing.) ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________________________________________________________________________________________ Download 65.1 Kb.
