    Does it make the water taste any better? I have a hot pot back at my dorm room and was wondering if i boil and cool it will it make the water taste any better than straight from the tap? I know it kills the bacteria to boil it but i've never heard whether the water will taste better.

    depends what you boil the water in, it may taste worse.

    possibly, some of the chlorine could evaporate/dissapate.

    It'll get rid of bacteria (works for if you're lost in the woods and find a stream) but it still won't rid the water of deposits like limestone and such.

    Usually tastes worse. Boiled water will usually have less oxygen in it, I think that must account for part of it.

    You'd basically boil the air out of the water. When you cool it back down, it'll taste flat.

    The bacteria would still be in the water (but dead). The minerals would still be in the water (and have flavor).

    Overall, I'd say the taste difference would be very small but detrimental.

    Just get one of thoe water filtration systems in a jug to get rid of bad taste.

    I'm not sure, i think boiling water causes minerals to precipitate out, those asian water boilers, after using it for a while, the bottom becomes caked in a thick sort of scaley/mineral deposit.

    Thats true, but how long is he going to boil his water? That, and we don't know what is caked and what stays in the water.

    I'm too lazy to google so OP is on his own. :D

    I've noticed boiled water tastes worse. I'm used to Brita filtered water and boiled water just has a strange taste to it. I'm not sure if this is a result of the boiling or the not-filtering, though.

    it's on wiki if one searches by "hard water", which is water high in minerals.

    i think it says limestone mostly precipitates out when you boil it.

    I think you might have read it wrong.

    In any case, it only comes out from the water that was boiled, which kind of defeats the purpose of the OP boiling water to drink it.

    stuff might leech out of the vessel you're boiling the water in, affecting its taste.

    it says lime is calcium hydroxide


    "Temporary hardness
    Temporary hardness is hardness that can be removed by boiling or by the addition of lime (calcium hydroxide). It is caused by a combination of calcium ions and bicarbonate ions in the water. Boiling, which promotes the formation of carbonate from the bicarbonate, will precipitate calcium carbonate out of solution, leaving water that is less hard on cooling.

    It should be noted that the above explanation is an oversimplification of the process that is occurring. The following equilibrium reaction actually happens when calcium carbonate (CaCO3) is "dissolved" in water:

    CaCO3 (solid) + H2O (liquid) + CO2 (gas) ? Ca2+ (aqueous) + 2 HCO3- (aqueous)

    Upon heating, less CO2 is able to dissolve into the water. Since there is not enough CO2 around, the reaction cannot proceed from left to right, and therefore the CaCO3 will not "dissolve" as readily. Instead, the reaction is forced to go from right to left (i.e. products to reactants) to reestablish equilibrium, and solid CaCO3 is formed. Heating water will remove hardness as long as the solid CaCO3 that precipitates out is removed. After cooling, if enough time passes the water will pick up CO2 from the air and the reaction will again proceed from left to right, allowing the CaCO3 to "redissolve" in the water."

    "Limestone is a sedimentary rock composed largely of the mineral calcite (calcium carbonate: CaCO3)."

    Well I had an idea for truely clean water but it would require a lot of energy, basically what you'd do is boil water and collect the percepitation from the act of boiling into another container, that way it should be cleaner, no?

    boiled water will taste worse than tap because of oxygenation. the more oxygen in the water, the better it will taste.

    i dunno but with my past experience in camping I seem to remember it always being worse then regular water from a tap. This could be for reasons like O2...or it could be the pot you boil it in.

    OR you could buy distilled water

    Drinking distilled water is not advisable. It'll leach minerals out of your body.

    Much of that site is BS, including that specific article.

    What the hell is the point of providing references if you don't note where they're used?
