That is true initially. However the distilled water will dissolve carbon dioxide from the atmosphere forming a mild carbonic acid with a ph at 6 or below.Distilled water is NOT acidic unless something else is dissolved in it. Pure water has a pH of 7.0 which is totally neutral, neither basic or acidic.....Bob L
distilled water is reactive, the ph may come out at anywhere from 4 to 8, however because the content of dissolved solids is low the ph can be manipulated quite easily, if you where to drink distilled water you would eventually die, your body takes the calcium from your bones and uses it to make contact points for the neuro receptors in your brain, no calcium no sanity no recall, this is alzheimers, tainted calcium in your receptors, water is the universal solvent, pure straight h2o is not containable by any known means, it is also not able to be achieved in this earth environment, the closer you get to straight the more reactive, the more reactive the more the universal solvent reacts until it reaches a non reactive state, I love plumbing, ask me about microbial intestinal parasites and waterborne bacterial life, I have watched a 5 pound fish dissolve in a parasitic bacterial cloud in 15 minutes, drink from a creek, not me!
Well that cheered me up no end!
I just realised why I never drink water!
That is called "buffering" and it has its uses, but not in auto cooling systems. The problem is that all of the metals in the system are also reactive and will exchange ions with whatever is dissolved in the water and corrosion cells will be caused wherever there are dissimilar metals or air/water interfaces. You need to use anti-freeze for its increased boiling point and its corrosion inhibitors....Bob LIf distilled water is highly reactive, then wouldn't mineral saturated tap water be better, provided that the ph was adjusted close to neutral?
Thats it! I'm filling my rad with pool water!
I agree with most of you ,I have pretty much used distilled water and some anti-freeze in the last 30 years,some places you can't drink the tap water, would you put that in your flat head,I don't Harold, central coast Ca.
