Card 1विद्युत रसायन का परिचय

विद्युत रसायन क्या है?

Answer

विद्युत रसायन, स्वतःस्फूर्त रासायनिक प्रतिक्रियाओं के दौरान जारी ऊर्जा से बिजली के उत्पादन और गैर-स्वतंत्र रासायनिक परिवर्तनों को लाने के लिए विद्युत ऊर्जा के उपयोग का अध्ययन है।…

Card 2Introduction to electrochemistry

What is electrochemistry?

Answer

Electrochemistry is the study of production of electricity from energy released during spontaneous chemical reactions and the use of electrical energy to bring about non-spontaneous chemical transform…

Card 3Galvanic cells

What is the Daniell cell reaction?

Answer

Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(s). Zinc is oxidised at the anode and copper(II) ions are reduced at the cathode. The cell converts chemical energy into electrical energy.

Card 4गैल्वेनिक सेल

डेनियल सेल प्रतिक्रिया क्या है?

Answer

Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(s) । एनोड पर जस्ता का ऑक्सीकरण होता है और कैथोड पर कॉपर(II⟧) आयनों का अपचयन होता है। सेल रासायनिक ऊर्जा को विद्युत ऊर्जा में परिवर्तित करता है।…

Card 5गैल्वेनिक और इलेक्ट्रोलाइटिक सेल

जब बाहरी वोल्टेज 1.1 V से कम होता है तो डेनियल सेल में क्या होता है?

Answer

इलेक्ट्रॉन Zn से Cu की ओर प्रवाहित होते हैं, इसलिए Cu से Zn की ओर धारा प्रवाहित होती है। जस्ता एनोड पर घुल जाता है और तांबा कैथोड पर जमा हो जाता है। गैल्वेनिक सेल अभी भी काम करता है।…

Card 6Galvanic and electrolytic cells

What happens in a Daniell cell when external voltage is less than 1.1 V?

Answer

Electrons flow from Zn to Cu, so current flows from Cu to Zn. Zinc dissolves at the anode and copper deposits at the cathode. The galvanic cell still operates.

Card 7Galvanic and electrolytic cells

What happens in a Daniell cell when external voltage equals 1.1 V?

Answer

No current flows and no chemical reaction occurs because the external opposing potential balances the cell potential.

Card 8गैल्वेनिक और इलेक्ट्रोलाइटिक सेल

जब बाहरी वोल्टेज 1.1 V के बराबर होता है तो डेनियल सेल में क्या होता है?

Answer

कोई विद्युत प्रवाह नहीं होता है और कोई रासायनिक प्रतिक्रिया नहीं होती है क्योंकि बाहरी विरोधी विभव कोशिका विभव को संतुलित करता है।…
