Which one of the following is NOT a strong electrolyte?
A
HCl (hydrochloric acid)
B
KNO\(_3\) (potassium nitrate)
C
CH\(_3\)COOH (acetic acid)
D
NaCl (sodium chloride)
Verified step by step guidance1
Understand what a strong electrolyte is: a substance that completely dissociates into ions when dissolved in water, resulting in a solution that conducts electricity very well.
Identify the nature of each compound given: HCl is a strong acid and strong electrolyte because it fully ionizes in water.
KNO\(_3\) and NaCl are ionic salts that dissociate completely into their ions in aqueous solution, making them strong electrolytes.
CH\(_3\)COOH (acetic acid) is a weak acid, meaning it only partially ionizes in water, so it does not produce as many ions as a strong electrolyte would.
Therefore, CH\(_3\)COOH is NOT a strong electrolyte because it does not fully dissociate into ions in solution.
