Nernst equation
E = E0 – .0592/n log (K)
Which electrolyte half-reaction is reversed in a spontaneous
electrolytic cell?
The half-reaction with the
least positive voltage.
How are electrons transferred in an oxidization half-
reaction?
The electrons are lost.
Bronsted-Lowry acid-base theory states:
The hydrogen donor is the acid and the hydrogen acceptor is
the base.
In net ionic equations, what is the rule for strong
substances?
Strong substances automatically dissociate
in water and do not form.
What are the four steps in balancing
half-reactions using the ion-electron
method?
1. Balance all elements except H and O.
2. Balance O with H2O.3. Balance H with H+.4. Balance the charges of
both sides by adding electrons to the more positive side.
