B.) Solid sodium chloride is a good conductor of electric current.
C.) Sodium chloride has a low melting point.
D.) Liquid sodium chloride is a good conductor of electric current.
NaCl solutions are electrically conductive because they are a powerful electrolyte in which the constituent ions completely separate, resulting in free-moving ions in the solution.c Thus, option D is correct.
The ions (Na+& Cl) are free to move around and can thus function as charge carriers, since the motility of individual atoms or molecules in liquid state is significantly larger than that of solid state. Because of the free ions, molten sodium chloride is a good conductor of electricity.
The charged particles (ions) in solid “[NaCl]” cannot move because they are bound by powerful electrostatic forces, making it a poor conductor of electricity. They cannot conduct electricity as a result.
Therefore, NaCl solutions are electrically conductive because they are a powerful electrolyte in which the constituent ions completely separate, resulting in free-moving ions in the solution.

D. because sodium chloride is an ion
first of all , sodium chloride is salt and we all know that it is not malleable.
sodium chloride is an ion which do conduct electricity but not when they are solid.....they only do so when they are molten or aqueous ( dissolved in water )
sodium chloride is an ion. ions have high melting points.
D is true because as i have mentioned above , ions will conduct electricity when dissolved in water / aqueous or molten.......... HOPE IT HELPED !!!!!!

1. Rainbow (white light is split into its subsequent wavelengths)
2. Light enters through the cornea, is adjusted by the lens, the cones and rods of the retina are responsible for the perception of color and shadows, which are sent through the optic nerve to the occipital lobe of the brain.
3. Sound waves are intercepted by the pinna, travels through the auditory canal, reverberates on the eardrum, the vibrations travel through the ossicles of ear (hammer, anvil and stirrup), continuing to the cochlea and are sent through the auditory nerve to the brain.
