corrosion occurs at the anode in a galvanic cell.
where does corrosion occur in a galvanic cell?
at the anode
in chemistry, a cathode is the electrode of an electrochemical cell at which reduction occurs; a useful mnemonic to remember this is anox redcat (oxidation at the anode = reduction at the cathode). another mnemonic is to note the cathode has a 'c', as does 'reduction'. hence, reduction at the cathode. perhaps most useful would be to remember cathode corresponds to cation (acceptor) and anode corresponds to anion (donor). the cathode can be negative like when the cell is electrolytic (where electrical energy provided to the cell is being used for decomposing chemical compounds); or positive as when the cell is galvanic (where chemical reactions are used for generating electrical energy). the cathode supplies electrons to the positively charged cations which flow to it from the electrolyte (even if the cell is galvanic, i.e., when the cathode is positive and therefore would be expected to repel the positively charged cations; this is due to electrode potential relative to the electrolyte solution being different for the anode and cathode metal/electrolyte systems in a galvanic cell).
