For melting point determination, what is the optimum rate of heating near the melting point? What are the problems, if the rate of heating is too slow or fast?

  • Chemistry/Ochem -

    1 to 2 degrees celsius per minute. If it is too fast, you can overestimate the melting point, and if you are trying to determine the range, the range wil be narrower then it would be at a slow temperature.

  • Chemistry/O-Chem -

    The end of the sentence in the above post should say slower temperature rate.

  • Chemistry -

    Generally 1-2 degrees per minute...if too slow it will take time for d mp to b gotten n if too fast temp change will b tooo rapid for accurate readings to b taken 4rm d thermometer....a slower rate of heatin is advisable 4 better observation
