This is totally conjectural, and I'm not really sure there would be enough solutes to make a difference. You can read here for a discussion about the impact of boiling on water pH, though I don't think it quite answers your question. | |
| Apr 11, 2019 at 20:59 | comment | added | theforestecologist♦ | @Ben, a discussion about the impacts boiling has on water pH is really more appropriate for Chemistry.StackExchange, so I'd advise you to ask that question there. | |
| Apr 11, 2019 at 20:54 | comment | added | Ben | I had hoped that boiling the water would be sufficient to bring the levels of dissolved CO2 to a consistent low level. I am fairly convinced that this would not work reliably - after looking further into sulfuric and nitric acids as described in your answer, so I think this answer is correct. I think this answer would be even better if it addressed what if any effect boiling would have on the amounts of these impurities. | |
