  • Galvanic Cell
    A spontaneous electrochemical system generating electricity via redox reactions, functioning similarly to a battery.
  • Voltaic Cell
    A device where chemical energy is converted to electrical energy through spontaneous redox processes.
  • Anode
    The electrode where oxidation occurs, electrons are lost, and mass decreases as the cell operates.
  • Cathode
    The electrode where reduction occurs, electrons are gained, and mass increases due to ion plating.
  • Salt Bridge
    A pathway containing neutral ions that maintains charge balance and completes the circuit in electrochemical cells.
  • Oxidation
    A process involving the loss of electrons, typically occurring at the negative electrode in a galvanic cell.
  • Reduction
    A process involving the gain of electrons, typically occurring at the positive electrode in a galvanic cell.
  • Electron Flow
    The movement of electrons from the negative electrode to the positive electrode, driving the cell's electrical output.
  • Ionization Energy
    The energy required to remove electrons from an atom, influencing how easily the anode loses electrons.
  • Electron Affinity
    A measure of how strongly an atom attracts electrons, affecting the cathode's ability to gain electrons.
  • Standard Cell Potential
    A value indicating the likelihood of redox reactions, determining the cell's strength as an oxidizing or reducing agent.
  • Half Reaction
    A representation of either the oxidation or reduction process, showing electron transfer at each electrode.
  • Plating
    The accumulation of ions onto the electrode surface, increasing its mass during reduction at the cathode.
  • Dead Battery
    A state where the cell has reached equilibrium and can no longer produce electrical energy.
  • Neutral Ion
    An ion that is neither acidic nor basic, commonly used in the salt bridge to balance charge without affecting pH.
