Substances which allow the electricity to pass through them are called
(a)
An example of a strong electrolyte is:
Ammonium hydroxide
Acetic acid
Sodium hydroxide
Urea
Substances like sugar, urea etc. the solutions of which do not conduct electricity are
known as
Insulators
Conductors
Weak electrolytes
Non electrolytes
On increasing the temperature, the dissociation of an electrolyte increases, hence conduction
Decreases
Remains constant
Increases
Temperature has no effect on electrolytic conduction
According to Ohm's Law, If to the ends of a conductor, a voltage 'E‘ is applied and a current ‘I‘ flows through it, then the resistance 'R'
E x I
I/E
E/I
None of the above
According to Ohm's Law, the SI unit of Resistance is =
(a)
Conductance is the reciprocal of
(a)
The (a) conductivity of a solution at a dilution V is the conductance of
all the ions produced from one gram equivalent of the electrolyte
dissolved in V cm3 of the solution
when the electrodes are one cm apart and
the area of the electrodes is so large that the whole of the solution is contained between them.
Debye Huckel-Onsager equation is found to hold good
at
High Concentrations
Moderate concentrations
Low concentrations
Does not hold good at change of concentrations
Debye Huckel-Onsager equation curve obtained for a weak
electrolyte shows that there is a very large
increase in conductance with dilution especially near
zero dilution
small dilution
large dilution
infinite dilution
