pH values for refrigerants
Hi, I am looking for pH (acid-base scale) values for following refrigerants: R22, R134a, R404A, R407C, R410, R507, R717 (NH3), R744 (CO2). Where can I get the information? Thanks in advance!
Best Regards,
Upender

Probably from the manufacturers?
Sorry, I don't know of any other source of the info offhand.

I had a look on their data sheets and I can't find any reference to PH
