The kinetics of hydrolysis of acetylsalicylic acid (aspirin) under certain conditions of temperature, pH, type of buffer and strength ionic, can be followed by multicomponent spectrophotometry. When performing a calculation of optical constants, the following data were obtained: Solution C. mg/100 mL A in λ (276nm) A in λ (290nm) Ac. acetylsalicylic ( AAS) 0.202 0.102 0.031 Ac. salicylic (AS) 0.198 0.158 0.101 Reaction: AAS + H2O → AS + CH3COOH In a kinetic study, after a certain time, 1 mL of the solution was taken from the reactor and diluted to 10 mL with water. distilled. Then when proceeding to the spectrophotometric measurement, the last solution presented the absorbances of 0.244 and 0.102 for the lengths of 276 and 290 nm respectively. What are the concentrations of ASA and AS in mg/L, at that instant in the reactor? Note: Acetic acid does not absorb at either wavelength.

Mercury(II) forms a 1:1 complex with triphenyltetrazolium chloride that exhibits an absorption maximum at 255 nm. The mercury(II) in a soil sample was extracted into an organic solvent containing an excess of TTC , and the resulting solution was diluted to 100.0 mL in a volumetric flask. Five-milliliter aliquots of the analyte solution were then transferred to six 25-mL volumetric flasks. A standard solution was then prepared that was 5*10^-6 M in . Volumes of the standard solution shown in the table were then pipetted into the volumetric flasks, and each solution was then diluted to 25.00 mL. The absorbance of each solution was measured at 255 nm in 1.00-cm quartz cells. Please solve and explain these questions: A.) Enter the given data pictured above into a spreadsheet and show the correct standard additions plot B.) Determine the slope and the intercept of the line C.)Determine the standard deviation of the slope and the intercept. D.) Calculate the concentration of Hg(II) in the…
