Electrolysis

Electrolysis is defined as the process of breaking down ionic compounds into their constituent elements by passing a direct electric current through the compound in a fluid state. The cathode reduces cations, while the anode oxidizes anions. An electrolyte, electrodes, and some form of external power source are the main components required for conducting electrolysis. A partition, such as an ion-exchange membrane or a salt bridge, may also be used, but this is optional. These are primarily used to prevent the products from diffusing near the opposing electrode.

Question

**The pH of an aqueous solution of 0.0327 M ascorbic acid, H₂C₆H₆O₆ (aq), is [______].**

In educational settings, this statement is typically followed by an illustration of how to calculate the pH of a weak acid solution using known values such as the acid dissociation constant (Ka) for ascorbic acid. This involves setting up an equilibrium expression for the dissociation of ascorbic acid in water, calculating the concentration of hydrogen ions [H⁺], and then using the pH formula:

\[ \text{pH} = -\log[\text{H}^+] \]

**For Detailed Explanation:**

- **Molarity (M)** refers to the concentration of a solution expressed in moles of solute per liter of solution.
- **Ascorbic Acid (H₂C₆H₆O₆)** is a weak acid commonly known as Vitamin C.
- The pH value indicates the acidity or basicity of the solution, with lower values being more acidic.

Educational websites might provide interactive calculators or step-by-step examples to help users understand the calculation process.
