Question

Choose the statement below that is TRUE. Question 7 options: The term "strong electrolyte" means that the substance is extremely reactive. The term "weak electrolyte" means that the substance is inert. A weak acid solution consists of mostly nonionized acid molecules. A strong acid solution consists of only partially ionized acid molecules.

Answer 1

Answer: A weak acid solution consists of mostly nonionized acid molecules.

Explanation:

Strong electrolytes are those solutions which undergo complete dissociation when dissolved in water. The dissociation of strong electrolytes is given by a right arrow.

Weak electrolytes are those solutions which do not undergo complete dissociation when dissolved in water. The dissociation of weak electrolytes is given by a rightleft arrow.

Weak acids are those substances which dissociate partially to give $H^+$ ions when dissolved in water. Thus most of molecules remain unionized in solutions.

$CH_3COOH\rightleftharpoons CH_3COO^-+H^+$

Strong acids are those substances which dissociate completely to give $H^+$ ions when dissolved in water.

$HNO_3(aq.)\rightarrow H^+(aq.)+NO_3^-(aq.)$
