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.

Scientific studies have confirmed that L-ascorbic acid acts as a powerful reducing agent capable of reducing copper ions. This chemical process is not only a fundamental concept in redox chemistry but also has significant applications in material science and nanoparticle synthesis.
