Using sulfuric acid to test gold plated magnets?
I have a bunch of gold plated magnets that I got a while ago from K&J magnetics. I'm going to implant two of them soon and currently doing saline test (I am aware gold plating is not very reliable, but I decided to implant them anyway). When I started doing the test I also put one regular nickel plated magnet as a control. To my surprise, three days later it still barely shows any signs of corrosion.
So I've been thinking what if instead of waiting for weeks to make sure the coating is alright I use a stronger chemical? To my knowledge sulfuric acid shouldn't dissolve gold, so I did a short test run and sure enough, gold plated magnet didn't seem to react at all while a regular magnet was completely dissolved withing minutes.
Is it save to later implant magnets tested this way? Has this been done before?
