Beer’s law was used next to calculate the absorbance of they time over time as bleach was added. One the absorbance value was calculated‚ the concentrations were able to be determined also using Beer’s law. From here the rate constant was able to be calculated for each concentration and the average was 0.599M/s. Overall‚ the Rate Law=0.14[dye]1[bleach]0. Trends in the date show when concentrations of the dye and bleach were at their fullest‚ the rate constant was lower and the change in absorbance

Personal Reflection Paper Ramona McCarty HUM/114 July 31‚ 2013 Kamia Jackson Personal Reflection Paper As I think back to the beginning of my Critical Thinking course I did not think it would be so hard and critical‚ but was I so wrong. What I have learned in this class is that I am not the advanced thinker that I thought I was. I did not know all of the issues that came along with actually knowing how to think critically or what you had to consider when solving problems and issues and how

To determine the rate law with respect to bleach and blue dye‚ a series of graphic and algebraic manipulations were done on the data obtained in the kinetic trace experiment in order to determine the different components that made up the rate law. Using absorbance spectroscopy to monitor concentration over time‚ rate order of the dye was found to be 1st order through the integrated rate law and through the proportionality method; the order of the bleach was also determined to be 1st order. Using

purpose of this lab was to determine the effectiveness of antiseptics‚ disinfectants‚ and antibiotics on bacteria. The hypothesis was that if bleach was used‚ it would be the most effective because bleach is commonly used to clean and disinfect various things. The variables that were tested were antibacterial soap and Scope mouthwash for the antiseptics; bleach and ammonia for the disinfectant; and Cipro‚ erythromycin‚ and tetracycline for the antibiotics. All of these chemicals were used on the bacteria

will demonstrate how a chemical reaction from vinegar‚ water‚ and bleach can accelerate the rusting process of steel. If steel wool pads are submerged in bleach‚ water‚ and vinegar‚ then the steel wool pads will rust faster in water because Electrolytes accelerate the corrosion process when combined with water. Materials and Procedure: you will need: Steel wool pads (the soap-free kind) 3 Medium sized jars Water Vinegar Bleach Procedure: 1. Place the steel wool pad into the jar. 2. Fill

were studied. Elodea was inserted into different beakers. One containing water and the other‚ bleach. The elodea was left unattended for an hour so that observations could be made to tell the difference in the results each beaker produced. After an hour the quantity of CO2 present was measured for the beaker with water and the beaker containing bleach. The results recorded were inconclusive because the bleach had a buffer that evidently lowered the pH‚ the beaker that had water in it showed signs that
