The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n Correct Answer: Chemical change<\/strong><\/p>\n\n\n\n Explanation:<\/strong><\/p>\n\n\n\n An electrolyte<\/strong> is a substance that produces ions<\/strong> when it is dissolved in water<\/strong> or molten<\/strong>, making the solution capable of conducting electricity. The correct answer is chemical change<\/strong>, because the process of ion formation involves breaking chemical bonds and forming charged particles\u2014ions\u2014which is a hallmark of a chemical change.<\/p>\n\n\n\n A physical change<\/strong> affects the form of a substance, but does not alter its chemical composition<\/strong>. For example, melting ice into water or dissolving sugar in water are physical changes, as no new substances are formed. In contrast, when an electrolyte such as sodium chloride (NaCl)<\/strong> dissolves in water, it dissociates into Na\u207a<\/strong> and Cl\u207b<\/strong> ions. This process involves breaking ionic bonds<\/strong>, leading to the formation of new species (ions)<\/strong> in solution. This is a chemical change<\/strong>.<\/p>\n\n\n\n Chemical changes involve transformations that result in the formation of new substances. In the case of strong electrolytes<\/strong> (e.g., NaCl, HCl, KOH), the compounds completely dissociate into ions:<\/p>\n\n\n\n This chemical dissociation<\/strong> is necessary for conduction of electricity. Weak electrolytes<\/strong> (like acetic acid, CH\u2083COOH) also undergo partial chemical dissociation into ions, which still qualifies as a chemical change.<\/p>\n\n\n\n A spontaneous change<\/strong> refers to a process that occurs without outside intervention, such as rusting. While some ionization processes may be spontaneous, spontaneity refers to the tendency of a reaction<\/strong>, not the type of change<\/strong> (physical or chemical). Hence, it’s not the best descriptor here.<\/p>\n\n\n\n Although different substances may behave differently (strong vs. weak electrolytes), all electrolytes produce ions via chemical changes<\/strong> in water or molten state. Therefore, it does not depend<\/strong> on the substance in terms of the type of change involved\u2014it is always a chemical change<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":" An electrolyte will yield ions by undergoing a: Select the correct answer below: physical changechemical changespontaneous changedepends on the substance The correct answer and explanation is : Correct Answer: Chemical change Explanation: An electrolyte is a substance that produces ions when it is dissolved in water or molten, making the solution capable of conducting electricity.
