I’ve got a clogged sink, and have been reading the labels on a bunch of different products lately. I’d always assumed that they were a strong acid of sorts, which would dissolve whatever sort of material was built up in the pipes. But I’ve noticed that a lot of these products specify that they’re non-corrosive, so I’m not sure what other sort of mechanism may be at play here.

    Bases were used because they were more compatible with the solder that connected copper pipes in older homes.

    Bases are much more effective at breaking up organic matter than acids. You can pour concentrated acid on your hand to little effect if you rinse it off quickly. You will not be able to do this with strong bases (think that scene from Fight Club). Strong bases rapidly destroy organic matter.

    If you need to dissolve a body, use lye, not some acid.

      I’ve stuck my hand in sulfuric acid and lye. No problem. You will instantly locate each and every microscopic cut on your hand. Sulfuric reacts with water to dilute instantly. Lye OTOH, yeah, takes a minute to get that off. But you will never see your hands so perfectly clean!

      And if y’all mess with either, wear some damned goggles. A glass of water to the eye will quickly fix sulfuric, but you’re screwed if you splash lye in there.

      Yep. Strong bases feel soapy to the touch, not because they are, but because they’re literally turning your skin into soap almost instantly.
