Electrolytic solutions are effective because they contain which of the following?

Electrolytic solutions are effective primarily because they contain more ions. In an electrolytic solution, ionic compounds dissolve in water to produce free-moving ions. These ions are responsible for conducting electricity within the solution.

When a substance dissolves and separates into its constituent ions, it enhances the solution's conductivity. The presence of a higher concentration of ions facilitates the movement of electric charge, which is crucial for processes such as electrolysis. In electrolysis, for instance, the presence of more ions is essential since it allows for the flow of electric current, leading to chemical changes at the electrodes.

In contrast, solutions with fewer ions, no ions, or only neutral molecules lack the conductive capability that is characteristic of electrolytic solutions. Without sufficient ions, the solution would not be able to support the flow of electricity effectively.
