Work with the best software developers who specialize in high-quality software engineering and can definitely add value to your organization. To conduct electricity, a substance must contain freely mobile, charged species. Solids dissolving in a liquid solvent (usually water in chemistry experiments) create a solution, and salt dissolving in water is a classic example of how a polar solute behaves in a polar solvent such as H2O. If the physical or chemical process that generates the ions is essentially 100% efficient (all of the dissolved compound yields ions), then the substance is known as a strong electrolyte (good conductor). Already noted was the polarity of both the water molecule, which you can imagine as roughly boomerang-shaped, and the NaCl molecule, which looks more like a short dumbbell.
