· In the burette, put the hydrochloric acid (concentration CA = 0,10 mol/L). · First of all, do a rough titration to get an idea where the end point is. · Now, do an accurate titration : run the hydrochloric acid in to within 2 mL of the end point, then add it dropwise.

hydrochloric acid. Another volume of 50 mL at pH 1.8 contained 0.3% (w/v) of pepsin. A control sample consisted of 50 mL of WPI solution at pH 7. Each solution was incubated at 37 °C during 4 h, then mixed with 50 µL of loading buffer to obtain 100 µL of sample. The loading buffer consisted of 2.5 mL of

Hydrochloric acid (37% Trace Select, Fluka), sodium chloride (99+% ACS reagent, Aldrich), and sodium hydroxide (10M Micro Select, Fluka) are used as received. About 10nM Cd(II) in 100ml of a 0.1M HCl solution is prepared by several dilutions of a 1gl−1 Cd(II) standard (Merck Eurolab). All other cadmium standards used to calibrate the method are
