CP1-TESTER QUIZ CHAPTER 2 Flashcards
Anions:
Are negatively charged ions
Which of the following is true about an electrochemical corrosion cell
As polarization increases current will decrease
The weight of any material deposited on the cathode or released from the anode is
Directly proportional to the amount of current flow
Oxidation
Occurs when the electrons are lost from an Atom or compound
electrochemical corrosion requires
Anode,cathode,electrolyte metallic path(electronic path )
In a anodic process
Positively charged ions leave the anode and enter the electrolyte
An electro chemical reaction consists of
Oxidation half reaction, A reduction half reaction, ionic movement in the electrolyte,electron movement in the metallic path
Resistance is measured in
Ohm’s
In a corrosion cell,electrons flow in the direction of
Anode to the cathode through the metallic path
Conventional current is in the direction of
Anode to cathode through the electrolyte
The reduction reaction that occurs in an electro chemical reaction
Occurs at the cathode, involves the gain of electrons
In the galvanic series, The more active metals
Will corrode if connected to a less active metal
In a corrosion cell,which of the following is not required
Oxygen
The portion of the metal that is corroding is called the
Anode
Cations:
Are positively charged ions
