Benedict's Solution

  1. Nov 6, 2005 #1
    Hello,

    I just have a quick question about Benedict's test...

    Why must the substance be boiled in order to get the results (change of color based on the percent of reducing sugar)???

    This is really bothering me! Please help if you can!

    Thanks in advance!
    PS

    I'm not familiar with the test, but from checking some sites I found using Google that explain the procedure, it looks to me like you just need to heat it to provide the energy for the reaction with Benedict's indicator to occur. Remember the concept of energy of activation for reactions from chemistry? Some reactions are not spontaneous at room temperature, so you need to heat them to provide sufficient energy for them to proceed. That's my best guess on this one. It also doesn't look like it's necessary to boil the solution, just heat it.
