Redox Rxns & stuff (chap 9)

Question 1

What are redox rxns

Answer 1

• if one atom or one is oxidized in a chemical reaction, another atom or ion must be reduced
• reactions in which electrons are gained by one atom or ion and lost by another

Question 2

What is a reducing agent

Answer 2

a reactant that reduces another reactant
~ reducing agent donates or loses electrons in a redox rxn and is oxidized

** look at oxidation # and if it increases (oxidation) then its a RA

Question 3

What is an oxidizing agent

Answer 3

a reactant that oxidizes another reactant
~ oxidizing agent recieves e- in a redox rxn and is reduced

*** look at oxidation # and if it decreases (reduction) then its a OA
