Silver is a metal with excellent beauty and conductivity, and is widely used in jewelry, electronics and industry. However, the requirements for its purity are different. The purity of traditionally traded silver is 99.99%, and electrolysis is a very good way to purify it.

The characteristics of 925 silver are that it does not deform and is durable. High-purity silver is widely used in the electronics industry.

Electrolytic purification uses potential difference and chemical reactions: Anode reaction (oxidation reaction):
Ag(s)→Ag⁺+ e﹣
Silver loses electrons at the anode to form silver ions (Ag⁺).
Cathode reaction (reduction reaction):
Ag⁺+ e﹣ →Ag(s)
Silver ions gain electrons at the cathode and are deposited as metallic silver.

Potential difference control: The standard electrode potential of silver is +0.7996V, but the actual operating voltage is usually between 2 and 5 volts to overcome solution resistance and other electrochemical resistances to ensure efficient deposition of silver. Thus, the purpose of purifying pure silver can be achieved.

Silver can be purified by electrolysis, and an automated control system can be further adopted to achieve unmanned operation and reduce labor.
