A weak electrolyte solution is one that partially ionizes in water, meaning it does not fully dissociate into ions. Looking at the options provided:
1. KCl (potassium chloride): KCl is a strong electrolyte because it completely dissociates into ions (K+ and Cl-) in water, forming a high concentration of ions.
2. Acetic acid solution: Acetic acid (CH3COOH) is a weak electrolyte because it only partially ionizes in water, producing a small amount of ions (H+ and CH3COO-) compared to a strong electrolyte.
Therefore, the solution that depicts a weak electrolyte solution is B. acetic acid solution.
