oxidation trivia questions
Oxidation is commonly defined as loss of what?
Answer: Electrons
Bonus fact: The mnemonic OIL RIG means Oxidation Is Loss, Reduction Is Gain.
Rusting iron is an example of what process?
Answer: Oxidation
Bonus fact: Iron loses electrons as it reacts with oxygen and water.
In terms of oxidation number, oxidation involves what change?
Answer: Increase
Bonus fact: Loss of electron density raises oxidation state.
In a discharging electrochemical cell, oxidation occurs at which electrode?
Answer: Anode
Bonus fact: A common chemistry mnemonic is 'An Ox, Red Cat': oxidation at the anode, reduction at the cathode.
At which electrode does oxidation occur?
Answer: Anode
Bonus fact: A useful mnemonic is An Ox: oxidation at the anode.
Oxidation and reduction always occur together in what kind of reactions?
Answer: Redox reactions
Bonus fact: One species loses electrons while another gains them.
In reduction, oxidation number generally does what?
Answer: Decreases
Bonus fact: Gaining electrons lowers oxidation state.
Oolong tea is generally what in terms of oxidation?
Answer: Partially oxidized
Bonus fact: Oolong styles span a wide oxidation range.
What happens to an element's oxidation number when it is reduced?
Answer: It decreases
Bonus fact: Electron gain makes the assigned oxidation state less positive or more negative.
At which electrode does oxidation occur in a voltaic cell?
Answer: Anode
Bonus fact: A common electrochemistry mnemonic is "An Ox, Red Cat": oxidation at the anode, reduction at the cathode.
Gold is prized for jewelry partly because it is very resistant to what?
Answer: Corrosion
Bonus fact: Gold is a noble metal and resists oxidation and tarnishing.
Which precious metals are commonly used as catalysts in converters?
