What is the relationship between salt concentration and light bulb brightness?

If you increase the amount of salt in the saltwater solution, the light bulb becomes brighter.)

Why do some compounds dissolved in water cause the bulb to light brightly?

An electrolyte is a substance that — when it is in an aqueous solution — conducts electricity because of the presence of free ions. When the solution is a strong electrolyte, the light shines brightly, but if the solution is a weak electrolyte, the light is dim. Nonelectrolyte solutions will not light the bulb.

How will Aqueous solutions of sucrose and sodium chloride differ?

The difference between the two substances is due largely to the fact that sodium chloride is an ionic compound, whereas sugar is a molecular one.

Is sodium chloride a conductor?

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. However in the molten state, ions in ionic compounds are free to flow and therefore molten sodium chloride can conduct electricity.

Why is sodium a good 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.

Does sodium chloride have Delocalised electrons?

These delocalised electrons are the mobile charged species in this case. Solid ionic compounds do have charged species e.g. Na+ and Cl- in NaCl, but they are not mobile and are fixed in an ionic lattice. This means they cannot conduct electricity.

Is sodium chloride conductive in water?

Common table salt (NaCl) is an electrolyte, and when this is dissolved in water to form salt water, it becomes sodium ions (Na+) and chloride ions (Cl-), each of which is a corpuscle that conducts electricity.

Can you manipulate magnetic field?

Physicists have managed to master magnetism—to create and manipulate magnetic fields—almost at will. Surprisingly, there is at least one property that has been elusive until now: how to ‘switch off’ the magnetic interaction of a magnetic material with existing magnetic fields without modifying them.
