Describe why digestion of the precipitate is a necessary step in gravimetric analysis.
Calculate the pH and pOH of a solution obtained by mixing equal volumes of 0.10M H2sO4 and 0.30 M NaOH.
How many millimeters of 0.500 M NaOH should be added to 10.0 g of tris hydrochloride to give a pH of 7.60 in a final volume of 0.250 mL? Useful information: Tris hyrochloride fw = 157.596 g/ml The Kb for tris is 1.2 x 10^-6 You can represent tris hydrochloride as BH+ and its conjugate base, tris, as B.
