Electrochemistry & Redox
Sacrificial Anode
A block of reactive metal attached to a structure so that it corrodes preferentially and protects the structure.
Electrochemistry & RedoxSalt Bridge
A conducting connection between the two half-cells of a galvanic cell that completes the circuit and maintains electrical neutrality.
Electrochemistry & RedoxSecondary Cell
A cell whose reaction can be reversed by an applied current, allowing it to be recharged and reused.
Electrochemistry & RedoxSelective Discharge
The preferential reaction of one ion over others at an electrode during electrolysis.
Electrochemistry & RedoxStandard Electrode Potential
The potential of a half-cell measured against the standard hydrogen electrode under standard conditions.
Electrochemistry & RedoxStandard Hydrogen Electrode
The reference half-cell, consisting of hydrogen gas at 1 bar bubbled over platinum in 1 M acid, assigned a potential of exactly zero.
