The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The correct answer is:<\/p>\n\n\n\n

Chemical change<\/strong><\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

Electrolytes are substances that dissolve in water (or another solvent) to produce ions, allowing the solution to conduct electricity. This process occurs through a chemical change<\/strong> rather than a physical change.<\/p>\n\n\n\n

A chemical change<\/strong> involves the breaking and forming of chemical bonds, leading to the formation of new substances with different properties. When an electrolyte dissolves in water, it undergoes dissociation (ionic compounds)<\/strong> or ionization (some covalent compounds like acids)<\/strong>, forming positively charged cations<\/strong> and negatively charged anions<\/strong>. This transformation is not just a simple phase change (like melting or boiling) but an actual reorganization of atoms or molecules at the chemical level.<\/p>\n\n\n\n

Examples of Electrolyte Dissociation:<\/h3>\n\n\n\n
    \n
  1. Ionic Compounds (Dissociation):<\/strong><\/li>\n<\/ol>\n\n\n\n
      \n
    • Sodium chloride (NaCl) dissolves in water and dissociates into sodium (Na\u207a) and chloride (Cl\u207b) ions:
      [
      NaCl (s) \\rightarrow Na^+ (aq) + Cl^- (aq)
      ]<\/li>\n\n\n\n
    • This is a chemical change<\/strong> because the ionic bonds in solid NaCl are broken.<\/li>\n<\/ul>\n\n\n\n
        \n
      1. Acids (Ionization):<\/strong><\/li>\n<\/ol>\n\n\n\n
          \n
        • Hydrogen chloride (HCl) dissolves in water and ionizes into hydrogen (H\u207a) and chloride (Cl\u207b) ions:
          [
          HCl (g) + H_2O \\rightarrow H_3O^+ + Cl^-
          ]<\/li>\n\n\n\n
        • This process is also a chemical change<\/strong> as new ions are formed through interaction with water molecules.<\/li>\n<\/ul>\n\n\n\n

          Why Not Physical Change?<\/h3>\n\n\n\n

          A physical change<\/strong> does not alter the chemical identity of a substance. For instance, melting ice to water is a physical change because no new substance is formed. However, dissolving an electrolyte in water changes its chemical structure at the molecular level, making it a chemical change.<\/p>\n\n\n\n

          Thus, the process of an electrolyte yielding ions is best classified as a chemical change<\/strong> because it involves the breaking of chemical bonds and the formation of charged particles.<\/p>\n","protected":false},"excerpt":{"rendered":"
