Pure silver electrodes are not inert electrodes

What is the material of pure silver electrode

Silver is not an inert electrode. Silver serves as an electrode to form an electroplating bath, while AgCl HCl forms an electrolyte equilibrium solution.

Inert electrode: an electrode that is not prone to electron gain or loss and generally does not react with the electrolyte. Composed of inert materials such as platinum, gold, or carbon and solutions containing soluble oxidized and reduced substances. It itself does not participate in redox reactions, only plays a role in transferring electrons. The electrode potential is equal to the potential of the redox pair in the solution.

Additional explanation: In an electrolytic cell, electrodes that do not participate in the reaction themselves are called inert electrodes, and vice versa are called non inert electrodes. Graphite, platinum and other electrodes are inert electrodes, while other electrodes are generally non inert electrodes. In an electrolytic cell, when metal or graphite is used as the cathode, the electrode itself cannot be reduced. The cation in the electrolyte solution undergoes a reduction reaction on the cathode. When the anode is an inert electrode, anions in the electrolyte solution are oxidized on the anode; When the anode is a non inert electrode, the electrode itself is oxidized. In addition, whether the electrode itself participates in the reaction depends on the reaction conditions. For example, graphite electrodes are inert electrodes at room temperature, but they are oxidized when used as anodes at high temperatures (industrial aluminum).

Pure silver refers to metallic silver with a content close to 100%. However, as silver is an active metal, it is prone to react chemically with sulfur in the air, producing silver sulfide that turns it black. Therefore, pure silver in daily life generally refers to silver with a content of 99.99%silverOr with a content of 92.5%925 sterling silver.
