(b)Strong electrolyte ionize completely at all dilutions and the number of ions does not increase on dilution. A small increase in \({ \wedge _m}\) volume with dilution is due to the weakening of electrostatic attraction between the ions on dilution.

Which of the following statements is not applicable to electrolytic conductors
1 New products show up at the electrodes
2 Ions are responsible for carrying the current
3 Show a positive temperature coefficient for conductance
4 A single stream of electrons flows from cathode to anode
Explanation:
(d)In electrolytic conductors, a single stream of electrons flow from cathode to anode.

Which one is not a conductor of electricity
1 \(NaCl\)(aqueous)
2 \(NaCl\) (solid)
3 \(NaCl\) (molten)
4 \(Ag\) metal
Explanation:
(b)In solid state \(NaCl\) does not dissociate into ions so it does not conduct electricity.

Solid sodium chloride is bad conductor of electricity because
1 It contains only molecules
2 It does not possess ions
3 The ions present in it are not free to move
4 It does not contain free molecules
Explanation:
(c)The ions are not free to move in solid state and held up in lattice due to strong coulombic forces of attraction.
(b)Strong electrolyte ionize completely at all dilutions and the number of ions does not increase on dilution. A small increase in \({ \wedge _m}\) volume with dilution is due to the weakening of electrostatic attraction between the ions on dilution.
