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

right to assemble. The women’s suffrage movement of the 1910’s in the United States is a classic example of how sociological change occurs. Portrayed in Iron Jawed Angels‚ the Suffragette Movement was a complex movement within the United States that underwent the five necessary stages needed for sociological change to occur. At the beginning of Iron Jawed Angels‚ a British suffragette Alice Paul along with Lucy Paul were talking with Carrie Chapman Catt in order to receive a permit to hold a parade

Potentiometric Titrations Accuracy The accuracy of a potentiometric analysis is limited by the measurement error for the cell’s potential. Several factors contribute to this measurement error‚ including the contribution to the potential from interfering ions‚ the finite current drawn through the cell while measuring the potential‚ differences in the analyte’s activity coefficient in the sample and standard solutions‚ and liquid junction potentials. Errors in accuracy due to interfering ions
