What is an effect of a strong electrolyte in solution?

A strong electrolyte is a substance that completely dissociates into its ions when dissolved in water. This complete dissociation allows the solution to contain a high concentration of charged particles (ions), which are essential for conduction of electricity. The ions in solution can move freely and carry electric current, making the solution a good conductor.

For example, when sodium chloride (table salt) is dissolved in water, it separates into sodium cations (Na⁺) and chloride anions (Cl⁻). The presence of these freely moving ions enables the solution to conduct electricity very effectively.

In contrast, the other options describe scenarios that do not apply to strong electrolytes. A strong electrolyte's ability to conduct electricity comes from its full dissociation into ions, which rules out any partial conductivity or inability to conduct. Additionally, while some solutes might form precipitates under certain conditions (such as when solutions are mixed), a strong electrolyte in solution typically remains fully dissolved, further reinforcing its ability to fully conduct electricity.
