Hello!

Can someone explain why pH is temperature dependent?
Really, I'm just worried about pHing 4% paraformaldehyde at about 50
degrees Celsius.  If I wait until it cools down to room temp, the para
usually precipitates--I assume because the pH is off.
I know I could measure the pH at room temperature, but I'm not making para
anytime soon, and I just thought of this.
By the way, the pH we are aiming for is 7.2 to 7.4
