corrosion
color of objects when corroded
orange,brown,red
which metal commonly rusts
iron
loss of electrons in a chemical reaction
oxidation
an element that must be present for corrosion to occur faster
water
covering metals with paint of plastic
coating
corrosion includes this type of reaction
what is oxidation
rust is chemically known as?
iron oxide
gain of electrons in a chemical reaction.
reduction
the gas essential for most corrosion reactions
oxygen
removing this element slows corrosion
water
corrosion is most common in?
what is metals
reddish brown color of rust is due to what chemical compound
hydrated iron(III) oxide
what term is the metal is usually in during corrosion
oxidized
when heated the rate of corrosion is
increased
metal used to protect iron in galvanization
zinc
corrosion weakens materials causing them to?
deteriorate, break apart, fail structurally
two substances required for rusting
oxygen and water
This type of reaction involves both oxidation and reduction
redox reaction
this substance in water increases corrosion rate by improving conductivity
salt
protection method using a more reactive metal
sacrificial protection
corrosion when metals reacts with water and oxygen together
electrochemical corrosion
rust is a specific type of corrosion that only affects this element
iron
oxygen is usually this during corrosion reactions
reduced
acidic environments increase corrosion due to high concentration of these ions
hydrogen ions
method where metal is electrically protected using another metal
cathodic protection
