Cu(NO₃)₂ eritmasi inert elektrodlar yordamida elektroliz qilinganda ajralgan metall konsentrlangan H₂SO₄ bilan reaksiyaga kirishdi. Hosil bo‘lgan gaz H₂S bilan ta’sirlashib 19,2 g oddiy modda hosil qildi. 1- va 2-reaksiyalar unumi 50% dan, 3-reaksiya unumi esa 100% bo‘lsa, elektroliz natijasida olingan misning miqdorini (mol) toping.

📝 Detailed explanation

3) SO₂ + 2H₂S → 3S + 2H₂O. n(S) = 19,2/32 = 0,6 mol ⇒ n(SO₂) nazariy = 0,2 mol. 2) Cu + 2H₂SO₄(k) → CuSO₄ + SO₂ + 2H₂O, unum 50% ⇒ amaliy SO₂ = 0,2 mol talab qiladi, ya’ni n(Cu)reak = 0,2/0,5 = 0,4 mol. 1) elektroliz unumi 50% ⇒ olingan mis = 0,4/... aslida shartga ko‘ra javob 0,4 mol mis.
