Test Preparation on Electrochemistry-II-Chemistry Test Series For NEET-2020

Which of the following shows electrical conduction

1Potassium
2Graphite
3Diamond
4Sodium

Graphite is a good conductor of electricity.

In infinite dilutions, the equivalent conductances of Ba²⁺ and
Cl^- are 127 and 76 ohm^-1cm^-1 eqvt^-1 . The equivalent
conductivity of BaCl2 at indefinite dilution is

1101.5
2139.5
3203.5
4279.5

Kohlrausch's law states that at

1Infinite dilution, each ion makes definite contribution to conductance of an electrolyte whatever be the nature of the other ion of the electrolyte
2Infinite dilution, each ion makes definite contribution to equivalent conductance of an electrolyte, whatever be the nature of the other ion of the electrolyte
3Finite dilution, each ion makes definite contribution to equivalent conductance of an electrolyte, whatever be the nature of the other ion of the electrolyte
4Infinite dilution each ion makes definite contribution to equivalent conductance of an electrolyte depending on the nature of the other ion of the electrolyte

Kohlrausch’s law states, “at infinite dilution each ion
contributes its fixed value towards equivalent conductance
irrespective of the other ion in combination with it at fixed
temperature.”
