\n\n\n\nExplanation:<\/h3>\n\n\n\n
\n\n\n\n
Electrolyte \u2013 Strong<\/strong>
NaOH is a strong base. When dissolved in water, it dissociates completely:
NaOH \u2192 Na\u207a + OH\u207b
Since it produces a high concentration of ions, it is a strong electrolyte<\/strong>, not a nonelectrolyte.<\/p>\n\n\n\n
\n\n\n\n
Electrolyte \u2013 Strong<\/strong>
HNO\u2083 is a strong acid. It fully ionizes in water:
HNO\u2083 \u2192 H\u207a + NO\u2083\u207b
Being fully ionized, HNO\u2083 is a strong electrolyte<\/strong>, not a nonelectrolyte.<\/p>\n\n\n\n
\n\n\n\n
Correct Answer \u2013 Nonelectrolyte<\/strong>
Ethanol is an alcohol. It dissolves well in water<\/strong> due to hydrogen bonding, but it does not ionize<\/strong>:
C\u2082H\u2086O \u2192 C\u2082H\u2086O (no ions formed)
It does not produce any significant number of ions and therefore does not conduct electricity<\/strong>. Hence, ethanol is a nonelectrolyte<\/strong>.<\/p>\n\n\n\n
\n\n\n\n
Electrolyte \u2013 Strong<\/strong>
KF is an ionic salt. It dissociates completely in water:
KF \u2192 K\u207a + F\u207b
This complete ionization makes KF a strong electrolyte<\/strong>, not a nonelectrolyte.<\/p>\n\n\n\n
\n\n\n\n
Electrolyte \u2013 Weak<\/strong>
Acetic acid only partially ionizes<\/strong> in water:
CH\u2083COOH \u21cc CH\u2083COO\u207b + H\u207a
It forms some ions, so it is a weak electrolyte<\/strong>, not a nonelectrolyte.<\/p>\n\n\n\n
