I understand the concept, but I can't seem to figure out the half reactions. Can someone please explain this to me?
Thank you in advance.

Thank you both. I guess my problems is recognizing which one is losing electron and which one is gaining. I just can't get a hang of it.
Can you please explain your technique?
For example, is my assumption correct here?
Given:
2Al + 3H2SO4 --> Al2(SO4)3 + 3H2
is this right?
Al --> Al3+ + 3e-
SO4 + 2e- --> SO4-2
Remember Cations will go to the Cathode. Cathode = Reduction = Gain of e- (this will go on the left side of the equation)
Al+3 + 3e- ---> Al
Then you have Anions which will go to the Anode. Anode = Oxidation = Loss of e- (this will go on the right side of the equation)
SO4 ----> SO4-2 + 2e-
Somebody please make sure I did this right, I dont want someone to memorize the wrong information lol.
Thank you so much guys! I'm getting them right now. Really appreciate it.
And thanks for that tip, toothhornet88. It works wonders. 😀
