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!
