Question

2. Which of the following statements is true?
(Points : 1)
A. Synthesis reactions occur at the anode.

B. Reduction reactions occur at the cathode.

C. Oxidation reactions occur at the cathode.

D. Combustion reactions occur at the anode.


I think it is C? But I am unsure.

Answer 1

B. I remember this by: A red cat and an ox. Red cat = reduction at cathode, and an ox = anode oxidation.

Answer 2

Yes, always remember:
Oxidation occurs at the anode; therefore the anode is negative since e- are lost (ANode OXidation).
Reduction occurs at the cathode; therefore the cathode is positive since e- are gained (REDuction CAThode).

Answer 3

Ok thanks you guys! :)

Answer 4

NP :)
