Step 1-2 on Redox RXNs in AQ solutions
use redox table to predict the products formed
use half-reaction method to balance equation after writing product formulas and statesRe
Redox Table
used to predict products formed
can determine if products or reactants are dominant if @ equillibrium
can tell if the mediums match (A = Acidic, B = basic, NA = not acidic, NB = not basic)
1st Factor to predict products
Arrows must line up
oxidizer in the left column must have an arrow pointing to the reducer column, or be reversible
reducer in right column must point left to oxidier, or be reversible
2nd factor to predict products
both reducer and the oxidizer must be in the same medium
ie. Acidic (A) + Acidic (A)
Acidic (A) + Not-Basic (NB)
Basic (B) + Basic (B)
Basic (B) + Not-Acidic (NA)
3rd factor to predict products
Redox reactions drive from stronger to weaker species
if reactants are stronger than products —> products favored
if reactants are weaker than products —> reactant favored
Oxidizers: stronger on top
reducers: stronger on the bottom
