What happens to fake gold in vinegar?
What happens when you put gold in vinegar? Real gold will shine while fake gold will change colors in reaction to the ascetic acid. Gold is a stable metal and does not react with oxygen corroding. Because it is stable, it will not change colors when exposed to vinegar.
Does gold float in water?
Gold is hydrophobic: it repels water. Because of this, even if the piece of gold is first completely submerged, if it gets near the surface it will throw off the water above it and float. Since most placer gold is flat and thin, its weight is small relative to its circumference so it will usually float.
What is gold attracted to?
Ordinary magnetic fields don’t attract gold, but a massive magnetic field can make this precious metal slightly magnetic.
