Question 1. a) You think that you have isolated a substance A in the lab. It melts at 75 – 77C. Since you don’t totally trust your own laboratory techniques, you wish to prove that you have substance A. Using only melting point techniques, explain how you can prove that you actually have this substance. b) List and explain how solubility is a factor throughout crystallization/recrystallization. c)Explain aspects of melting point as it is related to substance identityand substance purity
Note: The explanation of this work would be we did a work on the process of preparing diverse solution sets and regarding that these are the following sets of questions.
