Redox Reaction aur Electrochemical Cell

Redox Reaction ki Mool Baaten

• LEO-GER: Electron khone par oxidation (LEO) aur electron pane par reduction (GER).
• Redox Reaction: Oxidation aur reduction ki prakriya.
• Udaharan: Zn + CuSO4 → ZnSO4 + Cu
  • Zinc ka oxidation aur copper ka reduction.

Daniel Cell

• Daniel Cell: Zn aur Cu ke beech electron transfer dwara electricity utpann karta hai.
• Anode par oxidation aur Cathode par reduction hota hai.
• Electron movement se current utpann hota hai.

Salt Bridge ka Mahatva

• Salt Bridge: Electrode ke beech charge balance banaye rakhta hai.
• Salt Bridge ki sanrachna: Inverted U-tube jisme inert electrolyte hota hai.
• Upayog: Cell ki lagatar chalu rahne ki kshamata ko badhata hai.

Electrode Potential

• Electrode Potential (E): Metal rod aur electrolyte solution ke beech vibhavantara.
• Non-standard condition mein Nernst Equation ka upayog hota hai.

Electrolysis

• Vidyut urja se raasaynik parivartan aur synthesis.
• Cathode par cations ka reduction aur Anode par anions ka oxidation hota hai.
• Udaharan: NaCl ka electrolysis, jahan Na aur Cl₂ utpann hote hain.

Faraday Law

• Faraday First Law: W ∝ I × T (vajan current aur samay ke anupat mein hota hai).
• Faraday Second Law: Alag-alag electrolytes ke vajan unke equivalent vajan ke anupat mein hote hain.

Conductance

• Specific Conductance (κ): 1 mL electrolyte solution ki chalakkta.
• Molar Conductance (Λm): Diye gaye volume ke electrolyte ke moles dwara utpann conductance.
• Dilution ka Prabhav: Specific conductance ghatta hai, jabki molar aur equivalent conductance badhte hain.

Debye Huckel aur Kohlrausch Niyam

• Debye Huckel on Sagar Equation: Molar conductance ke liye upyogi.
• Kohlrausch ke Niyam: Infinite dilution par kisi bhi ion ka conductance fix hota hai.

Cell Efficiency

• Cell Efficiency: ΔG/ΔH
• Fuel Cell: Hydrogen aur oxygen se paani utpann kar urja deta hai.
