CHEM 103 Lab Notebook 3 Qualitative and quantitative analysis Portage/Experiment #: 3 Title: Quantitative Analysis and Qualitative Analysis. Purpose: Measure the quantity of a substance present in a chemical compound. Determine the identity of chemical substances. Procedure: Analyze a metal carbonate by weighing some of that carbonate into a beaker (a known amount), we will then put an excess of sulfuric acid in, then we will react the sulfuric acid with the carbonate. This will cause the ...

Homogeneous Mixtures Composition may vary; appears to be one substance, but really contains multiple materials; most are actually solutions Aqueous Solutions Have water as solvent, and solid, liquid, or gas as the solute Solutions Homogeneous mixtures Solute The component of the solution that changes state Solvent The component that keeps its state Entropy (Delta S): The measure of energy dispersal and disorder in the system Solvent-Solute Intera...
