Does pure gold oxidize(I truly need a long-time proffesional chemist)

In summary, the conversation discusses the oxidization of pure gold in different environments and at different temperatures. It is mentioned that pure gold takes thousands or even billions of years to completely oxidize at normal/room temperature in natural environments. The conversation also questions whether pure gold can oxidize on a molecular level in water, and if so, at what temperature. Additionally, there is a mention of the reaction between water and pure gold, as well as the possibility of sulfur reacting with water. The conversation concludes with a clarification on the term "molecular level" and the statement that gold is chemically inert at normal temperature and pressure, but can be dissolved by certain substances.

Some say pure gold oxidizes,but it takes thousands of years and even billions of years to completely oxidize on normal/room temperature i natural envirornments.
1.So,does pure gold in water(normal drinking and salt water) oxidize at least on molecular level i normal/room temperature?
Because on every website I've been so far,there is no a clue that pure gold oxidizes on molecular level(one atom supposedly reacts with oxygen in a few seconds).
2.And on which temperature pure gold oxidizes with oxygen,if pure gold doesn't oxidze on normal/room temperature?
3.And does water(drinking and salt) react with pure gold on normal/room temperature in natural environments?
4.Does sulphur react with water,myabe on molecular level?
Thanks!

What do you mean by "on molecular level"...?All chamical reactions take place at atomic/molecular level.

Daniel.

P.S.Gold in chemically inert at normal temp & pressure.Water,salted or not,does nothing to it.Royal water dissolves it though,giving auric chloride.

You can find explicit answers to these question within a standard general chemistry text, browse through the chapter on "metals."

gold can be dissolved by "aqua regia" (as alchemists used to call it), a solution of nitric and hydrochloric acid.
 

1. Does pure gold oxidize?

Yes, pure gold does oxidize, but it is a very slow process. Gold is known for its resistance to corrosion, but it can still react with certain substances over time.

2. How does pure gold oxidize?

Pure gold oxidizes through a process called oxidation, where it reacts with oxygen in the air or other substances. This process causes the gold to form a layer of oxide on its surface, which can change its appearance and properties.

3. What factors affect the rate of oxidation in pure gold?

The rate of oxidation in pure gold can be affected by various factors such as the purity of the gold, the presence of other substances or impurities, temperature, and exposure to certain chemicals or elements.

4. Can pure gold be completely resistant to oxidation?

No, pure gold cannot be completely resistant to oxidation. While it is highly resistant to corrosion, it can still react with certain substances over time. However, the rate of oxidation in pure gold is very slow, making it one of the most stable and unreactive metals.

5. How can oxidation in pure gold be prevented?

To prevent oxidation in pure gold, it is important to keep it clean and dry. Avoid exposing it to harsh chemicals or substances that can react with gold. You can also store it in airtight containers or use protective coatings to slow down the oxidation process.
