Yesterday in a school lab experiment, I accidentally splashed a really small amount of potassium dichromate solution (0.02000mol/L) on my hand. By "small amount," I mean a tiny drop that can't even visibly "run" due to gravity. Of course, I washed it off right after for a good amount of time. But am I still in any danger at all because of it? And are there any symptoms I should be aware of in case I got infected? I just wanted to make sure.
