This is because in solution the NaCl dissociates into Na+ & Cl- ions which get attracted toward oppositely charged electrodes & thus completing the circuit . Hence, the current flows .
This can't happen in solid state because in solid state there is lack of free ions & electrolyte {due to absence of water } & hence current can't pass.
No, solid NaCl cannot conduct an electrical current because ions are not free to move and carry the charge when in the solid state. Only in the molten or aqueous form can NaCl conduct electricity because the ions are mobile.
No, NaCl (sodium chloride) does not decrease when heated to 90 degrees Celsius. Heating NaCl at this temperature will not cause it to decompose or decrease in quantity – it will remain the same compound, only in a different physical state (solid to liquid).
one simple answer is that whan NaCl is solid the ions Na+ and Cl- are not free to move and conduct the electricity. when in a aqeous solution and as a liquid the ions are free to move and the electricity can be conducted. hope this helps
When a melted, we say it is in liquid state. However mercury is the only metal found in liquid state.
Sodium chloride (NaCl) is a bad conductor of electricity in the solid state because its ions are held tightly in a fixed position within the crystal lattice, so they are not free to move and carry an electric current. Only when NaCl is melted or dissolved in water does it become a good conductor of electricity, as the ions are free to move and carry charge.

The only non-metal that occurs in a liquid state at room temperatures is bromine (Br).
No DNA is in a solid state, only microscopic.
The only non-metal that occurs in a liquid state at room temperatures is bromine (Br).
Mercury is normally found in a liquid state at room temperature. It is the only metal that is liquid at room temperature.
In the liquid phase, only NaCl (sodium chloride) can be considered an electrolyte. When dissolved in water, NaCl dissociates into Na+ and Cl- ions, allowing it to conduct electricity. CO2, CuO, H2O (water), and H2O2 (hydrogen peroxide) do not dissociate into ions in the same way and therefore are not considered strong electrolytes in solution.
