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:<\/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 first understand what an electrolyte<\/strong> is. An electrolyte is a substance that dissolves in water to produce ions<\/strong>, allowing the solution to conduct electricity<\/strong>. Electrolytes can be strong<\/strong> (completely dissociate into ions) or weak<\/strong> (partially dissociate). In contrast, a nonelectrolyte<\/strong> dissolves in water without forming ions<\/strong>, so the solution does not conduct electricity<\/strong>.<\/p>\n\n\n\n Let’s analyze each option:<\/p>\n\n\n\n Electrolyte: Yes (Strong)<\/strong> Electrolyte: Yes (Strong)<\/strong> Electrolyte: No (Nonelectrolyte)<\/strong> Electrolyte: Yes (Strong)<\/strong> Electrolyte: Yes (Weak)<\/strong> Only ethanol (C\u2082H\u2086O)<\/strong> is a nonelectrolyte<\/strong> because it dissolves in water without producing ions<\/strong>, thus does not conduct electricity<\/strong>. All others are electrolytes because they produce ions\u2014either strongly or weakly\u2014in aqueous solutions.<\/p>\n","protected":false},"excerpt":{"rendered":" Which of the following is a nonelectrolyte?

\n\n\n\nExplanation:<\/h3>\n\n\n\n
\n\n\n\na) NaOH (sodium hydroxide)<\/strong><\/h3>\n\n\n\n
NaOH is a strong base and completely dissociates in water:
NaOH \u2192 Na\u207a + OH\u207b<\/strong>
Because it releases ions, it conducts electricity very well.
\u2192 Not a nonelectrolyte.<\/strong><\/p>\n\n\n\n
\n\n\n\nb) HNO\u2083 (nitric acid)<\/strong><\/h3>\n\n\n\n
HNO\u2083 is a strong acid and fully ionizes in water:
HNO\u2083 \u2192 H\u207a + NO\u2083\u207b<\/strong>
Since it forms ions, it’s a strong electrolyte.
\u2192 Not a nonelectrolyte.<\/strong><\/p>\n\n\n\n
\n\n\n\nc) C\u2082H\u2086O (ethanol)<\/strong><\/h3>\n\n\n\n
Ethanol is an organic alcohol. It dissolves well in water due to hydrogen bonding, but it does not ionize<\/strong> in solution.
It remains as neutral ethanol molecules:
C\u2082H\u2086O (ethanol) \u21cc C\u2082H\u2086O (ethanol)<\/strong>
No ions are produced, so it does not conduct electricity<\/strong>.
\u2192 This is the correct nonelectrolyte.<\/strong><\/p>\n\n\n\n
\n\n\n\nd) KF (potassium fluoride)<\/strong><\/h3>\n\n\n\n
KF is an ionic compound that dissociates completely in water:
KF \u2192 K\u207a + F\u207b<\/strong>
Ions are formed, and the solution conducts electricity.
\u2192 Not a nonelectrolyte.<\/strong><\/p>\n\n\n\n
\n\n\n\ne) CH\u2083COOH (acetic acid)<\/strong><\/h3>\n\n\n\n
Acetic acid is a weak acid. It only partially ionizes<\/strong> in water:
CH\u2083COOH \u21cc H\u207a + CH\u2083COO\u207b<\/strong>
Though only a small portion ionizes, it still produces ions.
\u2192 Not a nonelectrolyte.<\/strong><\/p>\n\n\n\n
\n\n\n\nSummary:<\/h3>\n\n\n\n
