It's pretty simple actually. All you need is some baking soda and a glass of water. First, place a small piece of the gold in the glass of water. Second, add enough baking soda to the water so that it covers the gold. Third, wait for a few minutes and then check to see if the gold has sunk to the bottom of the glass. If it has, then it is likely that the gold is real.
Are there any drawbacks to using this method?
There are a few potential drawbacks to using this method. First, it is possible that the sample size could be too small to be representative of the population. Second, there is always the potential for human error when taking samples and administering tests. Finally, results from lab experiments may not always be replicated in the field.

How do you know if gold is real?
There are a variety of tests you can use to determine if gold is real. The magnifying glass test is the easiest and most common. You simply place your gold in front of a magnifier, and see if it reveals any details or markings that would indicate its authenticity. The hallmark test is another common way to determine the authenticity of gold. This test involves identifying specific designs or letters located on the metal's surface. If the gold you're examining doesn't have these features, it's likely not genuine. Other tests include the skin test, float test, scratch test, and magnet test. The skin test involves applying pressure to a small area of the gold to see if it leaves an imprint; the float test measures how much water affects how much gravity pulls bodies of different weights down; scratch tests try to see if the metal can be scratched; and the magnet test tries to detect any magnetic properties in the metal. Ultimately, you need to use a combination
How to test gold with vinegar?
To test gold with vinegar, fill an eyedropper with clear vinegar and carefully put one drop on to a small piece of gold. If it turns different colors within seconds or minutes, then the gold has at least some silver in it and is not worth trying to melt down. Gold that is purely gold will not change colors when tested with vinegar.
