Sacrificial Anode
Electrochemistry & Redox
Dimensionless
A block of reactive metal attached to a structure so that it corrodes preferentially and protects the structure.
Salt Bridge
Electrochemistry & Redox
Dimensionless
A conducting connection between the two half-cells of a galvanic cell that completes the circuit and maintains electrical neutrality.
Secondary Cell
Electrochemistry & Redox
V
A cell whose reaction can be reversed by an applied current, allowing it to be recharged and reused.
Selective Discharge
Electrochemistry & Redox
V
The preferential reaction of one ion over others at an electrode during electrolysis.
Standard Electrode Potential
Electrochemistry & Redox
V
The potential of a half-cell measured against the standard hydrogen electrode under standard conditions.
E° at 298 K, 1 M, 1 bar
Standard Hydrogen Electrode
Electrochemistry & Redox
V
The reference half-cell, consisting of hydrogen gas at 1 bar bubbled over platinum in 1 M acid, assigned a potential of exactly zero.
2H⁺ + 2e⁻ ⇌ H₂, E° = 0.00 V
