Determination of an Unknown Concentration of Potassium Manganate using Colorimetry Introduction The purpose of this experiment is to conclude the concentration of an unknown solution using colorimetry to plot a calibration curve. Colorimetry measures the absorption of light at wavelengths within the visible region of the electromagnetic spectrum. It can be used to identify the unknown concentration of a solution in reference to a solution of a known concentration. When a solution appears

D. F. Nachman Thermochemistry: An Ice Calorimeter Determination of Reaction Enthalpy 9/11/2014 Introduction: A chemical reaction often indicated by a transfer of energy measured in heat. By measuring this heat transfer in a constant pressurized environment‚ the enthalpy of the reaction can be used to infer certain information about a specific reactions reactants and products. The transfer of heat from outside sources in would be described as an endothermic reaction. Contrary‚ when
