"I don't need a double blind test; the evidence is pretty conclusive."That's exactly why you do need one.
For an explanation on the effect of magnets you could have a read at the paper I had to post in a blog because the kind of people who says that magnets do not work dogmatically also refused to accept it: http://chemistry-f-talens-alesson.blogspot.com/.Essentially, ions in water have a bulk phase concentration and a surface excess. Surface excesses are often much higher, and they are the ones involved in reactions, including precipitation. Precipitation or other reactions will occur if the build up of those surface excesses reaches a critical value. That's what my paper is about, and also about how maths can deceive us into thinking that we know the mechanism of something when we only have a black box correlation.The magnets simply beat back the build up of the surface excesses and prevent the precipitation. But it can work the other way round: some companies sell devices for descaling of water prior to its use that usg magnets. What they are doing is forcing the build up to form faster in a tank with the help of the magnets. The decalcified water is then used.The bottom line is that magnets COULD be used to step up other reactions or to prevent them, for as long as the species involved or at least some of them are ionic.
water is ionic & freeze expansion is proof? Proper magnetization may work?
Is there something odd about this thread?I can't see my replies.
I certainly posted a reply to CARCZAR's post but it seems to have vanishedWater isn't ionic.The expansion on freezing isn't related to that fact and the ions responsible for hard water scale are not magnetic.
I was also big skeptic on this but the explanation that the magnetic field reduces the propensity to precipitate out, maybe somehow altering the way the crystals start to stack together, sounds quite plausible to me. This is lime scale I'm talking about, not Fe oxide

Everything is slightly magnetic, it's not inconceivable, but it's not been proven to work.
