Discussion Overview

The discussion centers around the oxidation behavior of pure gold, particularly in relation to its interaction with water and other substances at normal or room temperature. Participants explore whether pure gold oxidizes, the conditions under which it might do so, and its reactivity with various chemicals.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests that pure gold may oxidize, but only over extremely long timescales, such as thousands to billions of years, and questions its oxidation in water at normal temperatures.
  • Another participant questions the meaning of "on molecular level," asserting that all chemical reactions occur at that level and states that gold is chemically inert at normal temperature and pressure, indicating that water does not react with it.
  • A third participant suggests that standard general chemistry texts could provide explicit answers to the questions raised about gold's oxidation.
  • It is noted that gold can be dissolved by aqua regia, a mixture of nitric and hydrochloric acid, which implies that while gold is inert in many conditions, it can react under specific chemical environments.

Areas of Agreement / Disagreement

Participants express differing views on the oxidation of pure gold, with some asserting it does not oxidize under normal conditions while others suggest it may do so over very long timescales. The discussion remains unresolved regarding the specific conditions under which gold might oxidize.

Contextual Notes

There are limitations in the discussion regarding the definitions of oxidation and the specific conditions required for gold to react with other substances. The responses also reflect varying levels of detail and assumptions about chemical reactivity.

Who May Find This Useful

This discussion may be of interest to those studying chemistry, particularly in the areas of metal reactivity and oxidation processes.

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.
