Which of the following is a nonelectrolyte? Please state why or why not for each. Thanks<\/p>\n\n\n\n
a) NaOH
b) HNO3
c) C2H6O (ethanol)
d) KF
e) CH3COOH (acetic acid)<\/p>\n\n\n\n
The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n The correct answer is: c) C\u2082H\u2086O (ethanol)<\/strong><\/p>\n\n\n\n To determine which substance is a nonelectrolyte<\/strong>, we must understand what this term means. A nonelectrolyte<\/strong> is a substance that does not dissociate into ions<\/strong> when dissolved in water. As a result, nonelectrolytes do not conduct electricity<\/strong> in aqueous solution. In contrast, electrolytes<\/strong> (strong or weak) dissociate into ions and can conduct electricity.<\/p>\n\n\n\n Let\u2019s evaluate each option:<\/p>\n\n\n\n a) NaOH (sodium hydroxide):<\/strong> b) HNO\u2083 (nitric acid):<\/strong> c) C\u2082H\u2086O (ethanol):<\/strong> d) KF (potassium fluoride):<\/strong> e) CH\u2083COOH (acetic acid):<\/strong> Only C\u2082H\u2086O (ethanol)<\/strong> does not ionize in water and is therefore the only nonelectrolyte<\/strong> among the options provided.<\/p>\n","protected":false},"excerpt":{"rendered":" Which of the following is a nonelectrolyte?

This is a strong base<\/strong>. When dissolved in water, it completely dissociates<\/strong> into Na\u207a and OH\u207b ions:
NaOH \u2192 Na\u207a + OH\u207b
Because it produces free ions, NaOH is a strong electrolyte<\/strong> and conducts electricity well in solution.

This is a strong acid<\/strong>. It completely ionizes<\/strong> in water into H\u207a and NO\u2083\u207b ions:
HNO\u2083 \u2192 H\u207a + NO\u2083\u207b
As it yields ions, HNO\u2083 is a strong electrolyte<\/strong>.

Ethanol is an organic compound<\/strong> and an alcohol<\/strong>. Although it dissolves in water (due to hydrogen bonding), it does not dissociate into ions<\/strong>. Its molecular structure remains intact in solution.
Because it doesn’t produce ions, ethanol is a nonelectrolyte<\/strong>\u2014it does not conduct electricity<\/strong> in water.

\n\n\n\n
This is an ionic compound<\/strong> that completely dissociates<\/strong> in water into K\u207a and F\u207b ions:
KF \u2192 K\u207a + F\u207b
Thus, it is a strong electrolyte<\/strong>.
\u274c Not a nonelectrolyte<\/strong><\/p>\n\n\n\n
\n\n\n\n
This is a weak acid<\/strong>, meaning it partially dissociates<\/strong> in water into CH\u2083COO\u207b and H\u207a:
CH\u2083COOH \u21cc CH\u2083COO\u207b + H\u207a
While not fully ionized, it does produce some ions<\/strong>, so it is a weak electrolyte<\/strong>.
