Brown water!
It does in some water. I am not a chemist either, and I am simply too
old and busy with other stuff to dig out my chem books and start re-learning what I would need to know to work thru this. at least in soft acid water using calcium sulfate causes up and down PH swings. carbonate wont for the reasons you gave. perhaps sulfate has a much greater dissociation potential (I am grasping at parts of my memory have not been accessed for nearly 30 years!) It is like people used to recommend vinegar to acidify the water. Good idea, but it is organic and soon the water contains enough bacteria that uses acetic acid as a food.

It sounds good in theory, just doesnt work. Another Koivorkian moment. You're a scientist, Solo; you should know better. Plaster of Paris does not cause wild pH swings. It sounds good in theory, _and_ it works. It doesn't work in the _long_ term because the buffer gets used up, but it does work. |
