First of all, Merry Christmas everybody!
Just a quick question: What color is pure sulfuric acid? Wikipedia tells me it's clear and colorless, but maybe that's just an approximation?
I got some from a hardware store, and it's an oily brown color. It's concentrated enough that it doesn't eat metal very much unless you add water.
But got some "battery acid" today, and it's pretty clear, but not nearly as concentrated. (It doesn't even boil the water you add it to.)
So is the hardware store stuff impure, or is the battery acid version too dilute to show the color?
BTW, what is the scooby snack thing? Is it one of those reputation systems, where I give a snack to somebody who helps me?
