How to Test Platinum at Home With Vinegar

Platinum is one of the rarest and most expensive metals. It’s also very difficult to test because it doesn’t react with most chemicals. However, there is a simple test you can do at home using vinegar.

  • If you want to test platinum at home with vinegar, here are a few steps you can follow:
  • First, get a small sample of platinum
  • This can be done by purchasing a small piece of jewelry or asking a jeweler for a scrap piece
  • Next, pour some white vinegar into a bowl and place the platinum sample in the bowl
  • Allow the platinum to sit in the vinegar for about 15 minutes
  • After 15 minutes, remove the platinum from the vinegar and rinse it off with water
  • Finally, inspect the platinum to see if there is any change in coloration or appearance
  • If there is no change, then your sample is likely real platinum

Testing Platinum With Hydrogen Peroxide

If you’re looking to test whether or not your platinum is real, one of the easiest ways to do so is with hydrogen peroxide. Simply pour a small amount of hydrogen peroxide onto your platinum and wait for a reaction. If your platinum is real, it will immediately start bubbling.

Of course, this test won’t work if your platinum has been treated with chemicals that make it resistant to tarnishing. However, most untreated platinum should react to hydrogen peroxide. So if you’re unsure about the authenticity of your piece, this is a quick and easy way to find out.

How Can You Test Platinum at Home?

If you’re interested in testing whether a piece of jewelry is made from platinum, there are a few simple tests you can do at home. With just a few household items, you can test for the presence of platinum and get an idea of how pure it is. To start, gather together a magnet, some nitric acid, and some aqua regia.

Platinum is not attracted to magnets, so if your piece of jewelry sticks to the magnet, it’s not made from platinum. Next, use a small drop of nitric acid on the jewelry. If the metal changes color or dissolves, it’s not platinum.

Finally, use aqua regia (a mixture of nitric and hydrochloric acids) on the jewelry. If there’s no reaction or the metal doesn’t change color, it’s likely made from platinum. Keep in mind that these tests are far from definitive and shouldn’t be used to make final judgments about a piece of jewelry.

If you’re not sure whether something is truly made from platinum, it’s always best to take it to a professional for further testing.

How Do You Check If Platinum is Real?

When it comes to checking if platinum is real, there are a few key things you can look for. First, platinum is much heavier than other metals, so if you heft it in your hand it should feel significantly heavier than gold or silver. Second, platinum is very dense, so if you tap it with a hard object it will make a much sharper sound than other metals.

Finally, Platinum is non-reactive, so if you hold a magnet up to it, the magnet will not be attracted to the metal.

Can You Test Platinum With Hydrogen Peroxide?

Yes, you can test platinum with hydrogen peroxide. Platinum is a chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, gray-white transition metal.

Its name is derived from the Spanish term platino, meaning “little silver”.

How Can You Test Platinum With Acid?

There are a couple of ways to test platinum with acid. The most common way is to use aqua regia, which is a mix of hydrochloric and nitric acids. This will etch platinum and give you a good idea of its purity.

Another way to test platinum is with sulfuric acid. This will also etch the metal, but it’s not as effective as aqua regia.


If you’re interested in testing whether or not a piece of jewelry is made from platinum, there are a few household items you can use. All you need is some vinegar and a glass jar. First, fill the jar about halfway with vinegar.

Then, drop your piece of platinum into the jar and screw on the lid. Now, wait 24 hours before checking on your results. If the platinum has changed color or dissolved at all, it’s not real platinum.

However, if it looks exactly the same as it did when you put it in, congrats! You’ve got yourself a genuine piece of platinum jewelry.
