The unknown in this experiment is presumed to be something similar to acetaminophen‚ such as acetanilide or phenacetin. Recrystallization and melting point temperature were used to help identify the unknown in Panacetin. Recrystallization removes impurities as a substance goes through physical transformations from a solid to a liquid and back to a solid

Experiment Objective: To identify the components of an analgesic drug tablet and then correctly identify the tablet from a group of others with acquired data. Experiment Summary: In this experiment‚ we use TLC to identify components of an unknown analgesic drug. We prepare a solution of the drug by dissolving part of a tablet in 1:1 ethanol/dichloromethane‚ then spotting a TLC plate with the solution along with standard solutions of all active substances the drug tablet is likely to contain

Introduction: The objective of this experiment is to utilize the techniques of weighing and titrating to determine the total amount of MgSO4 present in an unknown sample. Standardized EDTA will be used to titrate the unknown solution. This type of reaction is a complexation reaction‚ which usually involves Lewis acids and bases. EDTA in complexation reactions serves as a chelating ligand. The base‚ EDTA‚ will bind to the metal ions‚ which serve as the Lewis acid‚ thus playing a role as a ligand

radiation emitted or absorbed by atoms and molecules. These studies are very helpful in determining an unknown element‚ given the fact that all elements burn a different color. The flame colors vary because of the different amounts of energy the elements give off. This lab is made for the learner to determine the identity of two unknown elements. Hypothesis If the color of one of the unknown elements is the same as one of the known elements‚ then they are the same element. Materials * Samples

Abstract: In this experiment‚ the specific heat and the density of an unknown metal was determined in order to identify the unknown metal. The average specific heat of the unknown metal was 0.197˚C and was determined using a calorimeter. The density of the unknown metal was 6.57 g/mL and was determined using a cylinder and displacement. Using the specific heat value of the unknown metal and its density‚ it was determined that the unknown metal was Tin. Introduction: The first law of thermodynamics states
