Electroplating

Electroplating involves passing an electric current through a conductive liquid, causing metal ions to move from the anode to the cathode. In this process, silver ions coat a copper spoon, creating a thin silver layer. This technique enhances corrosion resistance and appearance, often used to coat cheaper metals with silver or gold.

What initiates the electroplating process?

• An electric current

• A thermal process

• A chemical reaction

• A magnetic field

In electroplating, where do the metal ions move from and to?

• From the air to the liquid

• From the cathode to the anode

• From the anode to the cathode

• From the liquid to the air

What happens to silver ions at the cathode during electroplating?

• They are neutralized and form a layer of silver atoms

• They become charged and move back to the anode

• They evaporate into the air

• They dissolve in the liquid

What is one of the main purposes of electroplating?

• To make items lighter

• To change the color of the item

• To increase the weight of the item

• To make items more resistant to corrosion

Which metals are commonly used in electroplating to improve appearance?

• Iron and copper

• Silver and gold

• Aluminum and zinc

• Lead and tin
