Which statement best describes the characteristics of a 0.01 m KOH(aq) solution?
A
It does not conduct electricity because KOH does not dissociate in water.
B
It is a weak electrolyte and conducts electricity poorly.
C
It is a non-electrolyte and does not produce ions in solution.
D
It is a strong electrolyte and conducts electricity well.

Recognize that KOH (potassium hydroxide) is a strong base and an ionic compound that dissociates completely in water.
Understand that when KOH dissolves in water, it dissociates into K\(\textsuperscript{+}\) and OH\(\textsuperscript{-}\) ions, which are charged particles responsible for conducting electricity.
Recall that a strong electrolyte is a substance that completely ionizes or dissociates in solution, producing a high concentration of ions.
Since the solution is 0.01 m (molar), it contains a measurable concentration of ions, which allows it to conduct electricity well.
Therefore, the correct description is that the 0.01 m KOH solution is a strong electrolyte and conducts electricity well.
