Household chemical Qualitative Analysis Equation Using physical and chemical changes to determine the identity of 10 household chemicals.
Physical changes Physical properties can be observed or measured appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others. A physical change takes place without any changes in molecular composition.
Chemical Changes A CHEMICAL CHANGE alters the composition of the original matter. Different elements or compounds are present at the end of the chemical change. A chemical change is evident by one of the following: gas is produced a color change heat is produced or absorbed a change in odor
Conclusion Restate purpose of the lab. List evidence of physical changes taking place in any of the reactions. List evidence of chemical reactions that took place. Sources of error that might cause discrepancies in your data.
