This dissociation involves the breaking of chemical bonds or the formation of ions through a chemical process, not just a physical change.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Why not a physical change?<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A <strong>physical change<\/strong> involves changes in the state or appearance of a substance without altering its chemical composition. Examples include melting, boiling, dissolving sugar in water, or crushing a solid.<\/li>\n\n\n\n<li>When an electrolyte dissolves in water, if it were only a physical change, the substance would remain chemically the same in solution (like sugar dissolving). But electrolytes actually <strong>ionize<\/strong>, meaning the original molecules or ionic compounds break into charged particles (ions). This alters the chemical form of the substance in solution.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Why a chemical change?<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The process of an electrolyte dissolving often involves <strong>ionization<\/strong> or <strong>dissociation<\/strong>. For example, when sodium chloride (NaCl) dissolves in water, it dissociates into Na\u207a and Cl\u207b ions.<\/li>\n\n\n\n<li>This process involves the breaking of ionic bonds between sodium and chloride ions in the solid lattice and the formation of new interactions (hydration) between these ions and water molecules.<\/li>\n\n\n\n<li>The original compound Ceases to exist as intact molecules or formula units; instead, you have free ions, which is a chemical transformation.<\/li>\n\n\n\n<li>This ion formation is essential for the electrolyte\u2019s ability to conduct electricity in solution.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">What about &#8220;spontaneous change&#8221;?<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Spontaneous change<\/strong> refers to whether a process occurs naturally without added energy. The dissolution of electrolytes can be spontaneous or not depending on the specific compound and conditions.<\/li>\n\n\n\n<li>However, spontaneity is about thermodynamics and does not directly address whether the change is physical or chemical.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Does it depend on the substance?<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The nature of the change depends on the substance, but for <strong>electrolytes<\/strong>, the key defining feature is the chemical ionization process.<\/li>\n\n\n\n<li>Some substances dissolve physically (non-electrolytes), and some ionize chemically (electrolytes).<\/li>\n\n\n\n<li>For instance, sugar dissolves physically; NaCl dissolves chemically as ions form.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Summary<\/h3>\n\n\n\n<p>Electrolytes yield ions by undergoing a <strong>chemical change<\/strong> because ionization involves breaking and forming chemical bonds, changing the substance\u2019s chemical identity. This is fundamentally different from a physical change, which does not alter the substance&#8217;s molecular or ionic structure.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>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 : The correct answer is: chemical change Explanation: An electrolyte is a substance that dissociates into ions when dissolved in water (or another solvent) and thus conducts electricity.
