So you mean slightly basic is not superior to neutral (pH 7.0)? Or is either slightly acidic or basic better than neutral? I got to look into corrosion again. General Chem seems so long ago. lol But I thought a guide here said you wanted to keep your coolant on the basic side.
A little off topic, but you guys know about indicators right? It's the stuff that changes colors depending on the pH (and what particular indicator you use). Well I was reading during lab assistance work (got pretty boring in lab today) and apparently there's florescent indicators. In other words the color they emit when exposed to UV, or in some cases a sufficient concentration of visible light, changes depending on the pH. (A nonflorescent indicator would just change color.)
So I could get an indicator for the pH I would like and if my coolant starts looking greenish instead of blue, for example, I know my coolant is on its way out.
What do you guys think? Any fellow chemists out thre? (I'm working on a BA). I would add an appropriate buffer if I went this route to extend the coolants life.
