2 MnO^4- (aq) + 5 H₂C₂O₄ (aq) + 6 H⁺ (aq)    2 Mn²⁺ (aq) + 10 CO₂ (aq) + 8 H₂O (l)

Yup. Sixty degrees Celcius and the magic happens. What would happen at a lesser temperature, like 25°C? My first guess is that the reaction would be much slower, possibly enough to make a titration impossible. I'll be doing that reaction soon, without heating it. Lab procedure says so.

What do you think would happen at room temperature? Is the reaction titration-worthy in those conditions?

As far as I know this reaction is catalyzed by the presence of Mn²⁺, so it will be faster near the end of titration. As far as I remember - but it has been many years - it should work even at a room temperature, assuming you are patient.
