One day it was discovered that the waters of the lake were dead, estimated to be polluted Hg. How do you analyze whether it is true that the cause of death of this fish is due to the presence of mercury? What you would do as an analytic see this incident.Some standard solutions with concentrations of 2 ppm, 4 ppm, 6 ppm, 8 ppm and 10 ppm have absorbants of 0.1 each; 0,3 ; 0,5 ; 0,7 ; 0.9. Determine what the concentration of the sample if analyzed has absorbants of 0.32 and and 0.025. Explain how you analyzed it.A student wants to do a laboratory practicum by bringing students. In practicum you need sulfuric acid with a concentration of 0.1 N. While in laboratory there is sulfuric acid pa with a density of 1.84 gr / ml and 96 % w / w. Explain how you took the steps so that a 0.1 N sulfuric acid solution is available during practicum
