Science : How to fully clean silver at home & science You can use common household items: hot water, baking soda, salt, and an aluminum foil. It works thanks to electrolysis. When you mix hot water, baking soda, and salt with aluminum foil, a cool science trick called electrolysis comes into play. The aluminum acts as a sacrificial anode, meaning it gives up electrons more easily than silver. As a result, the aluminum oxidizes, releasing electrons. These electrons then flow through the silver, reducing silver ions back to silver. It's like a tiny electric current cleaning the silver by reversing the tarnishing process. In simple terms, the setup helps transfer electrons from the aluminum to the tarnished silver, making it shiny again. The salt increases conductivity, the baking soda raises pH to encourage metal precipitation and the hot water (heat) acts as a catalyst speeding things up How to clean silver at home & science Materials Needed: Aluminum foil Baking soda Sa
