leaks
Product contamination
loss of redundancy
appearance
increased regulation
◉ What is the definition of corrosion Answer: Deterioration of
material or properties because of reaction with its environment
◉ What is matter? Answer: Anything that occupies space
◉ What is an element? Answer: a substance that cannot be broken
down through chemical reactions
◉ What is a compound? Answer: combination of two or more
elements
,◉ What is a mixture? Answer: Combination of elements,
compounds, or both held together by physical forces
◉ What is an atom? Answer: The smallest chemical unit of an
element
◉ What is a molecule? Answer: The smallest particle of an element
or compound that retains all the chemical properties of that
compound or element
◉ What is an ion? Answer: A charged atom or molecule
◉ definition of electrolyte Answer: A liquid containing ions
◉ Characteristics of a anion Answer: Negative ion
net negative charge
formed by addition of electrons
attracted to anode
◉ Characteristics of a cation Answer: Positive ion
net positive charge
formed by loss of electrons
,attracted to cathode
◉ Examples of anions Answer: Sulfate ion
chloride ion
hydroxyl ion
◉ Examples of cations Answer: Ferrous ion
ferric ion
hydrogen ion
◉ Characteristics of oxidation Answer: Loss of electrons
increases positive charge
decreases negative charge
occurs at anode
electrons remain in metal
◉ Characteristics of reduction Answer: Gain of electrons
increases negative charge
decreases positive charge
occurs at cathode
metal is electron source
, ◉ Characteristics of anodic reactions Answer: Loss of electrons
increases positive charge
decreases negative charge
oxidation
electrons remain in metal
◉ Characteristics of cathodic reactions Answer: Gain of electrons
increases negative charge
