Yes.
You can check the density of the item in question to determine the amount of gold in the item.
You can check displacement by immersing the object in water and measuring the water level. (This was actually the first "eureka" moment.)
Measure weight with an accurate scale.

How can you tell if a gold ring is pure gold or has had some cheaper metal added to it without destroying or damaging the ring?
You can have the ring professionally tested using acid testing, electronic gold testers, or X-ray fluorescence analysis. These methods can determine the purity of the gold without causing damage to the ring.
What could you determine about a gold necklace that bubbles when it is exposed to an acid?
If a gold necklace bubbles when exposed to acid, it suggests that the necklace is not pure gold. Pure gold does not react with acid. The bubbling could indicate that the necklace is made of a lower karat gold alloy or a different metal that is reacting with the acid. It is recommended to have the necklace tested by a professional to determine its composition accurately.
Why will 14 carat gold turns black when testing with acid?
14 carat gold contains a higher percentage of other metals, such as copper, which can oxidize and create a tarnished black appearance when in contact with acid. The acid reacts with these other metals, causing a chemical reaction that results in the discoloration of the gold.
What could you determine gold necklace that bubbles when it is exposed to an acid?
If a gold necklace bubbles when exposed to acid, it likely means that the necklace is not pure gold, as pure gold does not react with most acids. The bubbling could be a result of a chemical reaction between the acid and a metal alloy used in the necklace. It is advisable to have the necklace tested by a professional to determine its composition accurately.
How do you determine if the gold is pure or not?
One common method to determine if gold is pure is through acid testing. A sample of the gold is tested with nitric acid, and its reaction or lack thereof can indicate the purity. Alternatively, professional jewelers may use tools like a spectrometer or X-ray fluorescence to analyze the composition of the gold accurately.
Does sulphuric acid remove copper from gold?
Sulfuric acid is not typically used to remove copper from gold, as it can also affect the gold itself. Other methods, such as leaching with cyanide or nitric acid, are commonly used to separate copper from gold. These methods are more selective in targeting the copper without damaging the gold.
How do you tell if your ring is real gold?
You can determine if your ring is real gold by looking for a hallmark or stamp indicating the purity of the gold (e.g. 14k, 18k). You can also conduct a simple at-home acid test, where real gold will not react to nitric acid. If you're still uncertain, consider getting it tested professionally by a jeweler.
What happened when you put gold plated gold in acid?
It becomes acid gold
Where can you play Pokemon gold online without downloading anything and are able to save your game?
In acid play
Was Rutherfords theory tested and published?
yes it was tested by the gold foil experiment
What happens if you put gold into sulfuric acid?
Gold does not react with sulfuric acid. Sulfuric acid is not strong enough to dissolve or react with gold under normal conditions. The gold will remain unaffected when exposed to sulfuric acid.
How do you know if your gold necklace is real gold?
By getting it tested by a jeweller.
