A THAM sample is contaminated with 7.64% sodium hydorgen carbonate, both of these are a monoprotic base. Assuming that it reacts completely, what quantative difference will this make in your calculations of the sulfuric acid molarity if your average result from the titration of three 0.350 g samples is 15.72 mL. Please explain your answer in detail (words and calculations).
I need help describing an experiment where one could measure the value of the extinction coefficient of a solution with a concentration (c mol/L) of chlorophyll in water for a given wavelength.
