Kudin Daniell da Karamin Ci Gaji na Batariya ta Daniell

Daniell Cell ita ce mai girma da Voltaic Cell. Mafi yawan Polarization wanda ke cikin Voltaic Cell ya zama fitaccen da ake iya ba da ita a Daniell Cell, saboda haka za a iya kira ta da fitaccen version da take bayyana Voltaic Cell. Daga tushen Daniell Cell ita ce mai tsawo.

Tushen Daniell Cell

Ita ce mai kyautar copper da take da shirya copper sulfate mai gajimat. A cikin kyautar, akwai kwal pot mai furuci da take da shirya sulphuric acid mai sauya, da ake juye a shirya copper sulfate mai gajima. Kamar zinc da ake amfani da shi ne a kan pot mai furuci da take da shirya sulphuric acid. Saboda halin shirya mai sauya, shirya sulphuric acid ta shahara da ions hydrogen mai mafi masu siffo da ions sulfate mai mafi yawa. Ions sulfate suna nemi wa zinc rod, suka bayar electrons zuwa rod, kuma suka yi zinc sulfate ta hanyar oxidation reaction. Saboda haka, zinc rod ya zama na mafi yawa kuma ya yi waɗannan da shi ne aiki a matsayin cathode.

Ions hydrogen mai mafi masu siffo suna iya jagoranci pot mai furuci kuma suka shiga shirya copper sulfate inda suka haɗa da ions sulfate daga shirya copper sulfate da suka samun sulphuric acid. Ions copper mai mafi masu siffo daga shirya copper sulfate suna nemi wa kofin kyautar copper inda suka bayar electrons ta hanyar reduction, kuma suka zama atoms copper kuma suka ci abin da suka haɗa a kofin kyautar.

Aiki a Daniell Cell

Za a bayyana aiki a cell ta hanyar steps don in fahimta.

A shirya sulphuric acid mai sauya akwai H+ da SO4– – ions.

Ions H+ suna jagoranci pot mai furuci kuma suka shiga shirya copper sulfate. Ions sulfate daga shirya sulphuric acid mai sauya suna haɗa da zinc rod inda Zn++ ions suna haɗa da SO4— ions kuma suka samun zinc sulfate (ZnSO4). A nan, har zuwa zinc an yi shiga electrons zuwa zinc rod. Saboda haka, zinc rod ya zama na mafi yawa, wanda yake yi waɗannan da shi ne a matsayin cathode.

Ions hydrogen (H+) a shirya copper sulfate suna samun sulfuric acid (H2SO4) kuma ions copper (Cu++) suna nemi wa kofin kyautar copper.

Ions copper suna ci abin da suka haɗa a kofin kyautar copper bayan suka bayar electrons daga kyautar. Saboda haka, kyautar copper ya zama na mafi siffo, wanda yake yi waɗannan da shi ne a matsayin anode. Idan ake haɗa external load zuwa zinc rod da kofin kyautar copper, electrons suna haɗa zuwa kyautar copper.

A Daniell Cell, muna iya bincike mafi yawan Polarization wanda shi ne mafi yawan Voltaic Cell. Saboda gas hydrogen ba a yi ci abin a anode saboda ta samu sulfuric acid a lokacin da ta shiga anode (kofin kyautar copper), ba za a iya samun layer da gas hydrogen a anode don in haɓaka reduction reaction.
