The standard addition method is used to analyze a sample of a river water for mercury. Solution A is made by pipetting 5.00 mL of undiluted sample in to a 10 ml volumetric flask and filling to the mark with DI water. Solution B is made by pipetting 5.00 mL of undiluted sample and 3.00 mL of 15.0 ppb of Hg standard into same 10.0 mL volumetric flask and filling to the mark with DI. Solution A and B are analyzed using atomic absorption spectroscopy and give a percent transmittance values of 56 % and 33 % respectively (not blank corrected). A blank has a transmittance of 96%. What is the corrected absorbance of both solution A and B? O A. Solution A: 0.123 Solution B: 0.463 O B. Solution A: 0.463 Solution B: 0.234 O. Solution A: 0.123 O D.

only SELECT correct respomses 1) Titrations of different forms are often employed to quantitate acids, bases, metal ions, and proteins. 2) To perform a titration, the experimenter must be familiar with the stoichiometry of the reaction taking place between the reagent and analyte. 3) Often in titrations, a visible color change will occur in the solution (due to an added indicator solution). 4) Gravimetric titrations directly measure the volume of reagent solution needed to react completely with an analyte. 5) For a monoprotic weak acid titration, the weak acid solution being titrated is the "sample" that is being quantitated. 6) For a monoprotic weak acid titration, the equivalence point is reached when the moles of added base equals the moles of weak acid originally present in the reaction vessel. 7) In a monoprotic weak acid titration, the weak acid is the analyte in solution, and a standardized base (for example, a solution of known concentration of NaOH) is the titrant. 8) A…
