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 identity and substance purity

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
