CHEM 113- Unit 5

ΔG when K is small positive (non-spontaneous)
ΔG when K is large negative (spontaneous)
redox reactions- acid solutions balance O with H2O, balance H with H+
redox reactions- basic solutions remove H+ with OH-, reconcile H2O's
anode oxidation (metal breaks down, more ions added to solution)
cathode reduction (metal builds up, ions removed from solution)
salt bridge allow transfer of ions (anions toward anode; cations toward cathode)
inactive electrodes electrodes made of something different than the solutions but still transfer electrons
2 most common inactive electrodes carbon, poladium, platinum
voltaic cell notation inactive electrode|lower ox state|higher ox state||higher ox state|lower ox state|inactive electrode
Ecell= cathode-anode
Voltaic cells are spontaneous when Ecell>0
Reduction potential is based off of standard hydrogen electrode
metal activity higher reduction potential=higher activity
concentration cell same metal at the anode and cathode-> differ in concentration (anode is always lower)
electrolytic cell external source of power must be greater than Ecell for the forward reaction
sign of oxidation in an electrolytic cell +
sign of reduction in an electrolytic cell -
molten salts: what forms at the anode LESS electronegative non-metal
molten salts: what forms at the cathode MORE electronegative metal

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
