fussyreader2yrCommentedIts mostly aqua regia
"No, it shouldn't be concentrated sulfuric acid. The reaction between sulfuric acid and metal will result in a passivation reaction. The dissolution will be very slow or even stop directly. If that's the case, they will die immediately. This couldn't be what the judge wants. Since this thing can dissolve metal and the dissolution speed can't be too slow, I think it is Wang Shui."- fussyreader2yrReplied to Knife_Monopoly
