There were several different concentration camps created between the 1930s and 1940s. Hitler’s main goal was to capture all of the Jews and assassinate them. He did not want any Jews to come out breathing after everything he planned to do. The Jews were most likely thinking that exact same thing. Hitler made thousands of camps all over Germany‚ stating that one was not enough. The first camp that he had ever established was called the Dachau. “The Dachau concentration camp was established in March

Being a partisan fighter Ben Kamm and i are just working in a concentration camp and then we get out. This was around 1946. It was in the poland area. We met some people in the camp that we became friends with but we had to leave them behind because we just don’t lie living in these condition. We could have brought him along but he is just too goofy and he would have got us caught. Ben and I hated being in a concentration camp. They made use work so hard. If you were sick they would kill you. If

Investigation: 20 How much cobalt is in the soil? Introduction: By completion of investigation 20‚ a standard curve of absorbance versus known cobalt (II) nitrate was prepared. The concentration of cobalt (II) ion obtained from a soil sample was determined. Whether or not cobalt nitrate should be added to the soil was determined. If cobalt nitrate needs to be added‚ then how much will it be required to meet the necessary nutritional needs of the animals was established. In colorimetry

glucosamine sulphate from tablets by UV-spectrophotometery. In this method‚ glucosamine sulphate was reacted with phenylisothiocyanate in presence of a base to yield phenylthiourea derivative. This derivative showed maximum absorbance at 240 nm. Beer’s law is obeyed in the concentration range of 5-25 µg/ml. The method was validated in terms of linearity‚ precision (relative standard deviation 1.1%)‚ accuracy and specificity. The proposed method is the only method available for spectrophotometric determination

Spectrophotometric determinations based on the Beer-Lambert Law are among the most widely used analytical procedures. These methods involve the measurement of the fraction of incident electromagnetic radiation that is absorbed by a sample. To determine the concentration of a colored species in solution‚ a cuvet containing the solution is placed in the spectrometer‚ which consists of a spectrograph and a photometer. The spectrograph produces light of selected wavelengths and is calibrated to indicate the color

experiment to study the relationship of absorbance and concentration‚ the interaction of electromagnetic radiant energy(ERE) and matter which is an important aspect of the Beer-Lambert ’s Law. This law states that the absorption of a compound is directly proportional to the concentration of that particular compound. This is because (a & b) are constants. In the equation‚ A = abc where A is the absorbance‚ a is the specific absorbance‚ b is the path length‚ c is concentration. This report presents the procedures

wavelength to study the absorbance of this salt was 500nm. It also demonstrated how transmittance of light and absorbance of light are inversely proportional because absorbance is calculated by multiplying transmittance by a negative log. Introduction: When one is studying chemicals‚ there are many important factors of significance. The color of a chemical is a useful tool in its study. The light one sees produced by a chemical is the result of both reflection and absorbance of wavelengths. The

Beer-Lambert Law INTRODUCTION Electromagnetic radiation can be described in terms of frequency (V) and wavelength (λ). Absorbance is the capacity of a substance to absorb radiation and transmittance (the fraction radiation at a specified wavelength that passes through a sample) is physical properties that all molecules have. The purpose of experiment one was to find the maximum absorbance (λmax) occurred for both bromophenol blue and methyl orange by using spectrophotometer. Spectrophotometer is a device
