Given a voltmeter readout, how do you determine which way
the electrons flow? - ANSWER-If the readout is a positive value,
then the electrons flow from left to right.
If the readout is a negative value, then the electrons flow from
right to left.
How do you balance a half reaction equation? - ANSWER-1.
determine the
oxidation numbers for all of the
numbers
2. balance the number of non H or O atoms
3. balance the number of electrons based on oxidation numbers
4. balance the number of oxygens with H2O
5. balance the number of hydrogen with H+
6. Check charge balance and atom balance
In order to have a complete half cell reaction, you must have
- ANSWER-no
,electrons in the final
equation
How do you find the K value in half-cell reactions - ANSWER-
K=10^((n*(E+-E-
))/0.059)
The half cell with the higher Eo tends to be - ANSWER-a
reduction equation
The half cell with the lower Eo tends to be - ANSWER-an
oxidation equation
The best reducing agents have - ANSWER-lower Eo values
The best oxidation agents have - ANSWER-higher Eo values
Reference Electrodes - ANSWER-maintain constant potential(V)
so that we are
able to determine the potential of a
different electrode
What are three examples of reference electrodes? -
ANSWER-Standard
Hydrogen Electrode
(SHE)
Silver-Silver Chloride
Electrode
, Saturated Calomel Electrode
(SCE)
What is the E of the Standard Hydrogen Electrode? - ANSWER-0
V
What is the E of the Silver-Silver Chloride Electrode? -
ANSWER-0.197 V
What is the E of the Saturated Calomel Electrode? - ANSWER-
0.242 V
What are indicator electrodes? - ANSWER-the electrodes that
are used in the
cell that are responsive to changes in analyte
concentration
What is a first order indicator electrode? - ANSWER-the ion that
you are looking
for is the same as the metal put in the
solution
What is a second order indicator electrode? - ANSWER-the
ion that you are
looking for is not the same as the metal put into
the solution
Liquid Junction Potentials - ANSWER-uses a salt bridge to keep
both half cells
