Question: Explain why salt and version can conduct electricity in solution?

Salt (like table salt, NaCl) and many other substances can conduct electricity when dissolved in water because they dissociate into ions. Here’s how it works:

Dissociation in Water: When salt dissolves in water, it breaks apart into its constituent ions. For example, sodium chloride (NaCl) dissociates into sodium ions (Na⁺) and chloride ions (Cl⁻).

Ion Mobility: These ions are charged particles that can move freely in the solution. The movement of these charged particles is what allows the solution to conduct electricity.

Electric Field: When an electric field is applied to the solution (e.g., by placing electrodes in the solution), the positive ions (cations) move towards the negative electrode (cathode), and the negative ions (anions) move towards the positive electrode (anode). This movement of ions creates an electric current.

In contrast, substances that do not dissociate into ions in water (like sugar) do not conduct electricity because they do not produce charged particles capable of carrying a current.

This ability to conduct electricity makes solutions of salts and other electrolytes crucial for many applications, from biological processes to industrial uses.
