Attachment 589898589896hi, can someone explain this question because I don't understand why the melting point of the pure product will differ from the actual data. I have no idea what you will observe either.

hi, can someone explain this question because I don't understand why the melting point of the pure product will differ from the actual data. I have no idea what you will observe either.
But what i can tell you hopefully shall help you.
When taking a mpt test.
You put your solid into a tiny tube and put it in the machine.
You observe the solid going to a liquid and record the temperature this happens at
Your sample is pure if, this value obtained, is close to that of the true value (ie: 1 exact temperature with a low percentage difference )
It is impure if it is within a range of temperatures or if it is far from the true value (high percentage difference )
Fingers crossed this helps, apologies for lack of specifism
