330010 Electrical conductance through metals are called metallic or electronic conductance and is due to the movement of electrons. The electronic conductance depends on

1 The nature and structure of the metal
2 The number of valence electrons per atom
3 Change in temprature
4 All of these
CHXII03:ELECTROCHEMISTRY

330011 Statement A :
Anhyd. HCl is bad conductor of electricity, while aq. HCl is good conductor.
Statement B :
Aqueous HCl is not fully ionised but anhyd. HCl is ionised to produce \({H^ + }\,\,and\,\,C{l^ - }\)

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
CHXII03:ELECTROCHEMISTRY

330012 Assertion :
The conductivity depends on the charge and size of the ions in which they dissociate, the concentration of ions or ease with which the ions move under potential gradient.
Reason :
The conductivity of solutions of different electrolytes in the same solvent and at a given temperature is same.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
CHXII03:ELECTROCHEMISTRY

330013 Which of the following statements is incorrect?

1 Both electronic and electrolytic conductance depends on the nature of conducting material
2 Both electronic and electrolytic conductance varies similarly with temperature
3 Electronic conductance is independent but electrolytic conductance depends on the amount of the conducting substance
4 All the above statements are incorrect
