of reaction of Alkali metals and Alkaline Earth meatals are compared in this lab. The pH of each of the resulting metal solutions are tested and the products of the reaction between calcium and water is discovered. The tested elements are sodium‚ lithium‚ potassium and calcium and each of them were placed in a beaker filled with water. The resulting solutions pH levels were tested with litmus paper. There were more steps for caclium because it is the only Alkaline Earth metal. For calcium‚ the gas

CHAPTER 5 DISCUSSION 5.1 Analysis of Trace Metal by FAAS Based on the table (4.3 and 4.4) the trace elements was detected by using the flame atomic absorption spectrophotometry analysis. The trace metal can be detected by the FAAS within 15 seconds to 30 seconds of each soil sample. Before the samples were analysis with the FAAS‚ the blank samples were run in the machine for each element that was being analyzed. Their absorbances were read. The mean of each blank was calculated and
