According to electrochemical principles, a calcium ion ($Ca^{2+}$) is a positively charged species that has lost two electrons. To understand what would reduce an ion of calcium, one must examine the methods to reverse this process by forcing the ion to gain back those two electrons, thereby returning it to a neutral calcium atom.

According to scientific literature, aqueous potassium hydroxide (KOH) is a common and highly effective type of alkaline electrolyte, known for its high ionic conductivity. This vital component is a conductive medium, facilitating the movement of ions to enable electrochemical reactions in various energy storage and conversion devices. Understanding its properties and applications is crucial to appreciating the technology behind everything from household batteries to large-scale hydrogen production.
