What is defined as an electrolyte?

• A. A substance that can conduct electricity in solid form
• B. A substance that conducts electricity when dissolved in water or when molten
• C. A substance that prevents the flow of electric current
• D. A substance that reacts with acids to form salts

Answer: (B)

The correct answer identifies an electrolyte as a substance that conducts electricity when dissolved in water or when molten. This is due to the presence of ions, which are charged particles that move freely in liquid solutions or molten states, allowing for the conduction of electricity. In solid form, many ionic compounds do not conduct electricity because the ions are held in fixed positions within the crystal lattice and cannot move freely. It is only when these compounds are dissolved in water or melted that the ionic bonds break apart, releasing ions into the solution or molten state, enabling electrical conductivity. Additionally, the other definitions provided do not accurately describe the nature of electrolytes. A substance that prevents the flow of electric current directly contradicts the fundamental characteristic of electrolytes. Likewise, a substance that reacts with acids to form salts describes a general acid-base reaction but does not specifically relate to the definition of electrolytes or their ability to conduct electricity.
