fat+dog Posted February 7, 2010 Report Share Posted February 7, 2010 Does temperature change the pKa of acetic acid?I heard that temperature kind of breaks down the acetic acid or something. Is that true?Can I use the titration method for this prac? Reply Link to post Share on other sites More sharing options...
Sandwich Posted February 7, 2010 Report Share Posted February 7, 2010 Google is your friend http://www.newton.dep.anl.gov/askasci/chem00/chem00920.htmI expect you could use titrations to determine the pH, although it would be difficult to do them all at different temperatures as they'd cool off to room temperature as you were going along.

Mahuta ♥ Posted February 7, 2010 Report Share Posted February 7, 2010 Yeah, everything is in that link.But I don't see it efficient to use titration, that's normally used when the only variables involved are the concentration and pH.Perhaps you could get the weak acid determined experimentally, then divide it into samples and investigate each sample with a different temperature. It's the first thing that popped into my head right now, so not really certain that it works. Reply Link to post Share on other sites More sharing options...
