If your water pH is high, it's possibly down to hardness. If you boil water, it precipitates out calcium carbonate, CaCO3, which causes temporary hardness. Logically this means pH should then drop, even if boil off occurs because what should be left is less dissolved calcium carbonate. Not only is this not the case but pH can in fact rise (I have found it does). Supposedly this is down to compounds that cause permanent hardness which doesn't precipitate out. However, calcium and magnesium chloride and sulphate are almost all below pH 7, this should be reducing the post boil pH of water.
So what compound(s) is/are concentrating to result in a higher pH than before?
I've tried searching the forum without any success, but maybe I've been looking for the wrong thing, so apologies if this has already been addressed. If any of the water chemistry books mentioned cover this, please let me know. I'm studying and so don't really have the time to be spent looking through books for information that might not be there.
