Again, I put this the New Hobbyists section. I don't think it will harm anyone to read it and this is probably the most active forum.
I have a few questions about pH and am confused as to why ro/di water has an acidic pH...or at least tests as though it does.
So pH or per hydrogen (potential hydrogen/potenz hydrogen) is caused by OH- and H+ ions. If there is more of one than another, then the pH will read something other than 7. I can accept that reverse osmosis fails to filter these ions and therefore affects the pH. However, deionization on the other hand should effectively remove these ions, giving the pH a neutral balance.
Am I right? Is my DI resin just dead? I do have 1 or 2 tds...
