### Sterling Silver Turning Black.

**Step 1: Oxidation**.

One of the main reasons sterling silver turns black is due to oxidation. When sterling silver comes into contact with oxygen in the air, a chemical reaction occurs that forms silver sulfide, which is black in color. This process is known as tarnishing.

**Step 2: Exposure to moisture**.

Moisture in the air can also contribute to the tarnishing of sterling silver. Humidity and moisture can accelerate the oxidation process, causing your silver items to turn black more quickly.

**Step 3: Chemical exposure**.

Exposure to chemicals can also cause sterling silver to tarnish. Chemicals such as perfume, lotions, and cleaning products can react with the silver and accelerate the formation of tarnish. In addition, exposure to sulfur-containing substances, such as eggs or rubber, can also cause silver to turn black.

**Step 4: Lack of care**.

Improper cleaning and storage of sterling silver items can also lead to tarnishing. If you don't clean your silver regularly or store it in a damp environment, it is more likely to turn black.

In conclusion, sterling silver turns black due to a combination of factors, including oxidation, exposure to moisture, and contact with chemicals. To prevent tarnishing, it is important to clean and store your silver items properly, and avoid exposing them to harsh chemicals. With proper care, you can keep your sterling silver looking shiny and beautiful for years to come.
