Question 6 (1 point) You are asked to test the electrolyte performance of several aqueous solutions<\/pre>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n
The correct answer is Na\u2082SO\u2084 > HCl > HCOOH > H\u2082O > CH\u2083CH\u2082OH<\/strong>.<\/p>\n\n\n\n
Here is the explanation:<\/p>\n\n\n\n
The strength of an electrolyte is determined by its ability to dissociate into ions when dissolved in a solvent like water. A higher concentration of ions results in a stronger electrolyte solution, which is a better conductor of electricity. We can rank the given substances by classifying them as strong, weak, or non-electrolytes.<\/p>\n\n\n\n
    \n
  1. Strong Electrolytes:<\/strong>\u00a0These substances dissociate completely, or almost completely, into ions.\n
      \n
    • 1 M Na\u2082SO\u2084 (Sodium Sulfate):<\/strong>\u00a0As a soluble ionic salt, sodium sulfate dissociates completely in water. Each formula unit produces three ions: two sodium ions (Na\u207a) and one sulfate ion (SO\u2084\u00b2\u207b). A 1 M solution yields a total ion concentration of 3 M, making it the strongest electrolyte on the list.<\/li>\n\n\n\n
    • 1 M HCl (Hydrochloric Acid):<\/strong>\u00a0As a strong acid, HCl also dissociates completely in water. Each molecule produces two ions: one hydrogen ion (H\u207a) and one chloride ion (Cl\u207b). A 1 M solution yields a total ion concentration of 2 M. While it is a strong electrolyte, it produces fewer ions per mole than Na\u2082SO\u2084, so it is ranked second.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Weak Electrolytes:<\/strong>\u00a0These substances only partially dissociate into ions, creating an equilibrium between the molecular form and the ionic form.\n
        \n
      • 1 M HCOOH (Formic Acid):<\/strong>\u00a0This is a weak acid. Only a small fraction of its molecules ionize in water to form H\u207a and HCOO\u207b ions. Its ion concentration is significantly lower than that of the strong electrolytes, making it a weak electrolyte.<\/li>\n\n\n\n
      • H\u2082O (Water):<\/strong>\u00a0Pure water itself undergoes autoionization (2H\u2082O \u21cc H\u2083O\u207a + OH\u207b), but to a very minimal extent. It produces a very low concentration of ions, making it a very weak electrolyte, weaker than the 1 M solution of formic acid.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • Non-electrolyte:<\/strong>\u00a0This type of substance dissolves in water but does not produce any ions.\n
          \n
        • CH\u2083CH\u2082OH (Ethanol):<\/strong>\u00a0Ethanol is a molecular compound. It dissolves in water due to hydrogen bonding, but it does not ionize. Since it produces no ions, it does not conduct electricity and is considered a non-electrolyte, making it the weakest on the list.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n
          Based on this analysis, the order from strongest to weakest electrolyte is: Na\u2082SO\u2084 > HCl > HCOOH > H\u2082O > CH\u2083CH\u2082OH.<\/p>\n\n\n\n
