2.0 mg 2390 mV 4.0 mg 2250 mV 6.0 mg 2170 mV 10.0 mg 2070 mV Table 1: This table represents the recorded data for the measurement of the measured potential; voltage, in the standard solutions with varying concentrations. The voltage was rounded to three significant figures. Figure 1: The plot of voltage vs. log nitrate concentration of the standard solutions created in lab. The correlation for the two is determined to be 0.9982 meaning there is a strong correlation between the two. The line of best fit was used in the second part of the experiment to interpolate the log of the concentrations of NA and NB samples. Validation Samples Voltage (mV) NA 1 2210 mV NA 2 2220 mV NA 3 2210 mV NB 1 2130 mV NB 2 2120 mV NB 3 2120 mV Table 2: This table represents the recorded data for the measurement of the measured potential; voltage, in the validation samples, NA and NB. Each sample had triplicated measurements represented by the subscript number next to each sample. The voltage was rounded to three significant figures. Validation Samples Log Concentrations Concentration Nitrate (mg/L N) Mean (mg/L N) Standard Deviation (mg/L N) NA 1 0.681 4.79 4.74 0.0685 NA 2 0.667 4.64 NA 3 0.679 4.78 NB 1 0.883 7.65 7.81 0.113 NB 2 0.898 7.91 NB 3 0.895 7.86 Table 3: This table represents the calculated results of the validation samples of NA and NB. The log concentrations of each sample was found by interpolating the calibration curve of the standard solutions. The nitrate concentration was found by taking 10 log concentration . The mean was calculated using the equation x m = x n while the standard deviation was found using the formula s x = ( d 2 n 1 ) 1 / 2 . Validation Samples (Class) Mean (mg/L N) Standard Deviation (mg/L N) NA 4.76 0.78 NB 8.00 1.15 Table 4: This table represents the class data for NA and NB. According to the class data, the average of NA is 4.76 mg/L, with a standard deviation of 0.78 mg/L, and the average of NB is 8.00 mg/L, with a standard deviation of 1.15 mg/L. Standard Solution Samples Voltage (mV) 1.0 mg 2230 mV 2.0 mg 2110 mV 4.0 mg 1990 mV 6.0 mg 1910 mV 10.0 mg 1810 mV Table 5: This table represents the recorded data for the measurement of the measured potential; voltage, in the standard solutions with varying concentrations of week 3. The voltage was rounded to three significant figures. Figure 2: The plot of voltage vs. log nitrate concentration of the standard solutions created in lab. The correlation for the two is determined to be 0.9991 meaning there is a strong correlation between the two. The line of best fit was used in the second part of the experiment to interpolate the log of the concentrations of NA and NB samples. Environmental Samples Voltage (mV) W 1 1970 mV W 2 1970 mV W 3 1970 mV B 1 1920 mV B 2 1920 mV B 3 1920 mV F 1 1970 mV F 2 1970 mV F 3 1960 mV Table 6: This table represents the recorded data for the measurement of the voltage in the environmental samples. W; Western Pond, B; Bluffs, and F; Formal Gardens. Each environmental sample had triplicated measurements which is represented by the subscript next to each sample. The voltage for each was rounded to 3 significant figures.  #### You've reached the end of your free preview.
