Final (Chapter 13) Flashcards
are solutions that show good conductance and which indicate a high degree of dissociation
strong electrolytes
solutions that exhibit only poor conductance and a low degree of dissociation
weak electrolytes
states that the electrolytes will dissociate into electrically charged particles, called ions, in such a manner that the total charge of (+) ions is equal to the total charge (-) ions
Arrhenius Theory of Electrolytic Dissociation
it states that each ion in the solution is surrounded by an ionic attraction whose net charge is opposite to that of the central ion
Debye-Huckel Theory of Interionic Attraction
branch of physical chemistry that concerns with the interrelations between chemical phenomena and electricity.
electrochemistry
the process of I passage through an electrolytic conductor with all the accompanying chemical and migratory changes
electrolysis
non-conductors of electricity with high resistivity
dielectrics or insulators
electrical resistance of a block of the material 1 cm in length and 1 cm^2 in cross section
specific resistivity
kinds of electrodes
cathode, anode
the electrode connected to the (-) side of the source of I by which electrons from this source enter the solution
cathode
the electrode connected to the (+) side of a source of I through which the electrons leave the solution to return to the source
anode
kinds of ions
anion, cation
ions which migrate toward the anode
anion
ions which migrate toward the cathode
cation
two types of conductors
electronic conductor, electrolytic conductor
conduction takes place by direct migration of electrons through the conductor under the influence of an applied potential
electronic conduction
examples of electronic conduction
solid and molten metals and certain solid salts
