Pure silver can tarnish but not as easily as Sterling Silver.

∙ 13y agoYes, pure silver can tarnish when exposed to air and moisture. Tarnishing is a natural oxidation process that causes a dull coating to form on the surface of the silver.
Sterling silver is a specific type of silver alloy that contains 92.5% pure silver and 7.5% other metals like copper. Silver, on the other hand, refers to the pure elemental metal. Sterling silver is often used in jewelry and silverware due to its durability and strength compared to pure silver.
Silver is a silver-white metal that does not tarnish easily due to its resistance to corrosion.
Silver does not react with water at room temperature. However, over time, silver may react with water and oxygen in the air to form a thin layer of tarnish.
Sterling silver tarnishes when it comes into contact with sulfur-containing substances in the air, such as hydrogen sulfide. This causes a chemical reaction that forms silver sulfide, the black tarnish you see on the surface of the silver. Factors like humidity, pollution, and certain foods can also accelerate tarnishing. Regular cleaning and proper storage can help prevent tarnish on sterling silver.
The "rust" of silver is tarnish. If you want to get technical, only iron truly rusts.

When silver oxidizes, it often develops a grayish-black color known as tarnish. This tarnish can diminish the metallic shine of silver objects but can be removed through polishing.
Oxidized silver is not necessarily sterling silver but sterling silver can be oxidized. Oxidation is a finish on silver, otherwise known as tarnish. Sterling silver can tarnish and silver plate can tarnish, too.
Karat (sometimes Carat) is the measure of purity of gold. 24 Kt is pure gold. Silver purity is expressed in % of silver. Sterling silver = 92.5% of pure silver. The remainder is usually copper. Pure silver is a little soft for table use, so copper is added to make the alloy stronger. But this does promote tarnish.
The word "tarnish" in the sentence "the silver will tarnish if it is not polished often" is a verb. It is describing the action of the silver in the sentence.

== == Tarnish is in no way indicative of a low quality in sterling silver. Sterling silver (or .925 silver) is, by law, at least 92.5% pure silver and no more than 7.5% other metals. Sterling silver is an alloy, or mixture, of metals. Pure silver is too soft to be used for most jewelry and household good purposes, so other metals are added to strengthen the metal and make it more durable. Pure silver oxydizes (tarnishes) very slowly, but the addition of other metals to pure silver cause it to oxydize (or tarnish) more quickly. Laws regulate how metals must be marked. In the US, only pure silver can be marked ".999" and only silver of at least 92.5% purity can be marked ".925" or "sterling."
Silver. The purer the silver the more rapidly it will tarnish.
Silver does not react with water at room temperature. However, over time, silver may react with water and oxygen in the air to form a thin layer of tarnish.
Sterling silver is pure silver adulterated with a small quantity of another metal. The inclusion of this other metal oftentimes is the cause of tarnishing. This explains why some silver pieces tarnish much more than others - it depends on the overall metal mix in the piece. You can actually develop an eye for different makers/time periods/regions of silver pieces due to this factor. For instance, vintage Taxco pieces have a very distinctive patina that differs from that of other period silversmiths, or even from modern Taxco. Pure silver shouldn't tarnish, retaining a very whitish, brilliant shine. It's difficult to find such silver jewelry; a good alternative is rhodium-plated sterling, which also doesn't tarnish easily.
It is a chemical change. Oxygen from the air combined chemically with the silver to form silver oxide- that is the tarnish.
Yes.
