Q-1: A) 0.50 mL of 96 % H2SO. (98 g/mol, density: 1.84 g/mL) was diluted 750 mL with ultrapure water. Calculate pH of this solution?
B) To prepare pH 2.3 bisulfate/sulfate buffer solutions, how much mL
of 2.52% (w/v) of KOH (56 g/mol) should
be added
to 500 mL of
above H2SO4 solution (a)? (If you cannot find the concentration of the
above diluted H SO,
solution (a), take the concentration of the diluted
H2SO4 solution as 0.015 M. In this case, the score of the question will
be 80% of the actual score) Kaj: .. Kaz:1.2x10-2
