1. Silver tarnishing (before cleaning): Tarnished silver is usually coated with silver sulfide (Ag₂S), which forms when silver reacts with sulfur compounds in the air. 2Ag+H2S→Ag2S+H22Ag + H₂S ightarrow Ag₂S + H₂2Ag+H2S→Ag2S+H2 Silver sulfide gives the silver a black appearance. 2. Aluminum and salt in the water: When you add water, salt (NaCl), and aluminum, an electrochemical reaction begins. The salt water acts as an electrolyte, facilitating the flow of electrons between the aluminum and silver. Aluminum is more reactive than silver, so it donates electrons more readily. The reaction can be summarized as: Oxidation (on the aluminum surface): Al→Al3++3e−Al ightarrow Al^{3+} + 3e^-Al→Al3++3e− Aluminum is oxidized, losing electrons and going into the solution as aluminum ions (Al³⁺). 3. Reduction (on the silver surface): The silver sulfide on the tarnished silver is reduced back to elemental silver by gaining the electrons released by the aluminum. Ag2S+2e−→2Ag+S2−Ag₂S + 2e^- ightarrow 2Ag + S^{2-}Ag2S+2e−→2Ag+S2− The sulfur ions (S²⁻) are released into the solution, and the silver (Ag) is restored to its original shiny state. 4. Baking soda's role (NaHCO₃): Baking soda helps to neutralize sulfur compounds and prevent further tarnishing. It can also slightly increase the pH of the water, making the reaction proceed more efficiently. The overall reaction between aluminum and silver sulfide in the presence of salt and baking soda can be written as: 3Ag2S+2Al+6H2O→6Ag+Al2O3+3H2S3Ag₂S + 2Al + 6H₂O ightarrow 6Ag + Al₂O₃ + 3H₂S3Ag2S+2Al+6H2O→6Ag+Al2O3+3H2S In this reaction: Aluminum displaces silver from silver sulfide. Silver returns to its shiny form. Hydrogen sulfide gas (H₂S) might form, but it's usually trapped in the solution. Thus, the combination of salt, baking soda, and aluminum leverages the reactivity series of metals to restore the silver without any damage. 4o window.__oai_logHTML?window.__oai_logHTML():window.__oai_SSR_HTML=window.__oai_SSR_HTML||Date.now();requestAnimationFrame((function(){window.__oai_logTTI?window.__oai_logTTI():window.__oai_SSR_TTI=window.__oai_SSR_TTI||Date.now()}))
