In the solid state, ionic compounds such as sodium chloride have their ions fixed in position and therefore these ions cannot move so solid ionic compounds cannot conduct electricity.
Why is NaCl a bad conductor of electricity in solid state?
Solid [NaCl] is a bad conductor of electricity because the charged particles (ions) in solid [NaCl] are not capable of moving as they are bound by strong electrostatic forces. As a result, they can not conduct electricity. … As a result, they can not conduct electricity.
Is NaCl a good conductor of electricity in solid state?
NaCl does not conduct electricity in solid state whereas it does conduct electricity in aqueous solution as well as in molten state.
Why is sodium chloride not a good conductor?
Sodium chloride in a solid state (i.e. table salt) cannot conduct electricity well because the ions in the substance () cannot move freely (they are immobile) albeit they can carry a charge, and thus electric charge cannot flow easily throughout sodium chloride. This idea holds true for all metals.
Which NaCl is bad conductor of electricity?
in solid NaCl there are no electrons. ionic solids are bad conductor of electricity.
Is Solid sodium a poor electricity conductor?
Solid sodium is good conductors of electricity as in sodium there is no band gap between the valence band and conduction band as they overlap with each other. The electrons are continuously available in the closed orbital which can conduct electricity.
What makes a bad conductor of electricity?
Conductors conduct electrical current very easily because of their free electrons. Insulators oppose electrical current and make poor conductors. Some common conductors are copper, aluminum, gold, and silver. Some common insulators are glass, air, plastic, rubber, and wood.
Why is NaCl a good conductor of electricity in water?
NaCl is an electrolyte. When in solution it dissociates into Na+ and Cl-. When you put electrodes in the solution, the cations are drawn to the cathode and the anions to the anode. This movement produces a current and that is why NaCl solutions can conduct electricity.
Which of the following is a poor conductor of electricity?
In option D, water being a liquid, its conductivity depends upon is dissociation into ions, but due to the low concentration of H+ and OH− ions, it is considered as a non-electrolyte and is a poor conductor of electricity. ∴ The correct option is option D, i.e. water .
Why is sodium chloride a good conductor of electricity but does not have any effect on litmus solution?
So the solution is must be a solution of neutral electrolyte. For example NaCl is a neutral electrolyte which has no effect on litmus paper and the solution of NaCl conduct electricity as NaCl ionises to its constituent ions.
Is NaCl a solid insulator?
Answer: In solid NaCl, the ions have fixed positions in the lattice structure and there are no free ions but in aqueous solution or molten state, the ions can move freely and thus conduct electricity.
Why solid copper chloride does not conduct electricity but copper chloride dissolved in water becomes a good conductor of electricity?
Electrons are bound in bonds by strong electrostatic forces. So, copper chloride does not conduct electricity in solid-state. On dissolving in water, the copper chloride dissociates into a copper ion and chloride ion and these ions conduct electricity.
Which substance is a poor conductor of electricity in solid form but can conduct electricity when in aqueous solution?
Electrolytes are salts or molecules that ionize completely in solution. As a result, electrolyte solutions readily conduct electricity.
