Concept explainers

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

To study the effects of a weakly acidic medium on the rate of corrosion of a metal alloy, a student prepared a buffer solution containing
both 0.150 M NaC₂H3O2 and 0.053 M HC₂H3O2. Calculate the pH of the buffer using the K₁ for C₂H3O₂. Be sure to write the chemical
equation for the equilibrium as the reaction of C₂H30₂¯ with water. Then use the chemical equation as a guide in setting up the
equilibrium expression for Kb.
For acetic acid, HC₂H3O2, K₂ = 1.8 × 10-5.
