Determination of Rate and Order of a Reaction Results This experiment used a spectrometer to find the wavelength with maximum absorbance in a green food coloring solution. For this particular solution the wavelength was 629.7 nm. The system was then calibrated to that and was set to measure the food coloring and bleach solution. The measured visible light absorbance of the mixed solution was collected over a time of 200 seconds and eight points were then selected and placed into the Absorbance

ABSTRACT The average concentration of CaCO3 obtained was 212 ppm‚ with a standard deviation of 1 ppt. The results indicate that the unk B tap water can be considered as hard water. INTRODUCTION Hard water is due to metal ions (minerals) that are dissolved in the ground water. These minerals include Ca 2+‚ Mg2+‚ Fe3+‚ SO42-‚ HCO3-. When this water evaporates or boils‚ the difficult to dissolve metal salts remain as a scaly residue. Hard water inhibits the effectiveness of soap and detergents

Determining the Percent Copper and Zinc in Pennies from Density Lab Report Procedure: For pre-1982 pennies- Mass 10 pennies‚ record data. Fill a 100mL graduated cylinder to 40mL or enough to fully submerge the pennies with water‚ record the volume in data table. Carefully place the pennies into the graduated cylinder‚ record the final volume of the water in data table. To find the volume of the pennies‚ subtract the final volume from the initial‚ record the data. Repeat this procedure twice more

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
