Watercooling coolant question

[Butterfish]

Hello, 

 

I found this coolant from feser one "Ultra pure water" and it says on the website im buying it from that the pH is 2-3. Isn't that eh... bad?

 

EDIT: This is taken from the site: 

 

"Feser Aqua has to first of all passed through the reverse osmosis system, and shortly after this into the downstreamed De-Ionized system. The PH-Value is 2.0 - 3.0 and lies in the acid ph-range."

That must be a mistake. Pure water is slightly acidic, but not that much.

 

Here's Speicaltech's listing: http://www.specialtech.co.uk/spshop/customer/Feser-Aqua-Ultra-Pure-Water-1-Litre-pid-4573.html

 

pH 5.5 - 6.5. That's the range I would expect.

It'd be bad since the fluids in your stomach are about that pH. But as ghost said probably a mistake
