Introduction:The experiment that was conducted on the previous lab day was "How Much Cobalt is in the Soil?" For this lab report the experimenters used a spectrometer to determine how much transmittance and absorbance different concentrations of a cobalt solution have. After finding the results the amount of cobalt is determined and then plugged into an equation to give the amount of cobalt in the soil.Conclusion:The wavelength that our lab group used was 430nm. In order to dilute the liquid used in the experiment we added water to the substance. For example, when the group needed a 10% solution 9 milograms of water was added to 1 milogram of the cobalt(II) nitrate. 430nmempty: 99.810%: 99.820%: 99.830%: 87.640%: 80.350%: 71.960%: 69.170%: 61.780%: 50.990%: 47.8100%: 41.3
