The Conductive Property of Sodium Chloride Solution

Answer: A. It is made up of ions that are held together by ionic bonds.

Have you ever wondered why a solution of sodium chloride in water is a good conductor of electricity? Let's delve into the science behind it!

Sodium chloride, commonly known as table salt, is composed of clear, colorless crystals. When sodium chloride is dissolved in water, it dissociates into sodium ions (Na+) and chloride ions (Cl-). These ions are held together by ionic bonds, where positively charged sodium ions are attracted to negatively charged chloride ions.

Now, this arrangement of ions in the solution allows for the easy movement of charged particles, enabling the flow of electric current. As a result, when an electric potential is applied across the sodium chloride solution, the ions can freely move towards the oppositely charged electrodes, completing the circuit and allowing electricity to conduct through the solution.

Conductors, like sodium chloride solution, play a crucial role in electrical circuits by facilitating the transfer of charges. The presence of ions in the solution enables it to conduct electricity efficiently, making it a valuable component in various applications, such as electrolysis and electroplating.

Therefore, the next time you encounter a solution of sodium chloride in water, remember the fascinating science behind its conductive nature and the role of ions in allowing the flow of electric current!
