Topic 11: Redox and electrochemistry
1. Redox: Recalling concept facts and definitions
1. A reaction that involve the losing and gaining of electrons is called
1) Fusion 2) Neutralization 3) Kinetics 4) Redox
2. A redox reaction always involves
1) A change in oxidation number 3) The transfer of protons
2) A change of phase 4) The formation of ions
3. Which particles are gained and lost during a redox reaction?
1) Protons 3) Neutrons
2) Electrons 4) Positrons
4. In all redox reactions, there is conservation of

1) Mass, but not charge 3) Both mass and charge
2) Charge, but not mass 4) Neither mass nor charge
5. All redox reactions involve
1) The gain of electrons, only 3) Both the gain and the loss of electrons
2) The loss of electrons 4) Neither the gain nor the loss of electrons
6. A redox reaction is a reaction in which
1) Only reduction occurs
2) Only oxidation occurs
3) Reduction and oxidation occur at the same time
4) Reduction and oxidation occur at different times
7. Which statement correctly describes a redox reaction?
1) The oxidation half-reaction and the reduction half-reaction occur simultaneously
2) The oxidation half-reaction occurs before the reduction half-reaction
3) The oxidation half-reaction occurs after the reduction half-reaction
4) The oxidation half-reaction occurs spontaneously but the reduction half-reaction does not
8. Which set includes only reactions that involve oxidation and reduction?
1) Synthesis, decomposition, and double replacement
2) Synthesis, decomposition, and single replacement
3) Decomposition, single replacement, and double replacement
4) Synthesis, single replacement, and double replacement
9. A redox reaction always involves
1) A transfer of protons
2) A change in phase
3) A change in oxidation number
4) The formation of ions
10. A charge an atom has or appears to have when it gains or loses electrons is called
1) Ionization number
2) Electronegativity number
3) Reduction number
4) Oxidation number
