maintains electrical neutrality
Standard electrode potentials are
reduction potentials
In a redox titration, an indicator that reacts with a particular reaction product or reagent is
called
specific

becomes...
sharper
,The thermodynamic cell potential is calculated by subtracting the
anode potential from the cathode potential
In an electrochemical cell at equilibrium, the cathode potential is always
the same as the anode potential
In a potentiometry cell, the electrode whose potential is independent of analyte concentration
is called
reference
The metallic indicator electrode whose linear response comes from the direct equilibrium with
the analyte is called
first kind
When a glass pH electrode deviates from typical response because of the low hydronium ion
concentration and presence of other ions its called the
alkaline error
