Acid-base calculations answers

Answers to Acid-base calculations questions 1. (a) 2.0 ; (b) 2.0 (pH depends on the hydrogen ion concentration not on the volume present).(c) 3.7 ; (d) 12.0(e) 2.7 (H2SO4 is diprotic so [H+(aq)] = 2.00 x 10-3 mol dm-3 and pH = – log10(2.00 x 10-3)(f) 11.3 ([OH–(aq)] = 2.00 x 10-3 mol dm-3 so pOH = 2.7 and pH = 14.0 − 2.7)2.(a) [H+(aq)] = 10-3.6 = 2.51 x 10-4 mol dm-3(b) Since [H+(aq)] x [OH–(aq)] = Kw = 1.00...
