Conclusion The purpose of this experiment was to discover the chemical properties that copper has when reacting with other chemicals and how it changes physically during these processes. (Department of Chemistry‚ 2013) This was achieved through many types of reactions‚ such as a redox reaction‚ double displacement‚ decomposition reaction and single displacement depending on the chemical properties in relation to copper of the other substances when it was added with copper. Copper was either in an

CHEM 1211 L Principles of Chemistry Lab 16 February 2004 Lab Report 1 Introduction The purpose of this project is to identify an unknown organic acid (X) by conducting various experiments to determine the acid’s unique properties. By determining selected constant properties of the unknown and then comparing these properties to the constant properties of known substances‚ it is possible to identify an unknown substance. The properties used to identify the unknown must be intensive‚ or independent
