The dissociation of arsenic acid is given by: H3ASO4(aq) + H2O(1) H2AsO4 (aq) + H2O(1) HASO42- (aq) + H2O(1) H2AsO4 (aq) + H30+ (aq) HASO42- (aq) + H30+ (aq) AsO43-(aq) + H30+ (aq) Ka = 5.5 x 10-3 (at 25°C) Ka = 1.7 x 10-7 (at 25°C) Ka = 5.1 x 10-12 (at 25°C) A. Classify the species, H3ASO4, H2AsO4, HASO42-, AsO43-, as acid, base, or ampholyte. B. Applying the systematic method in solving acid-base equilibria problems, calculate the pH of the following: 0.010 M H3ASO4 C. 0.010 M NazHASO4 b. 0.010 M NaH2AsO4 d. 0.010 M Na3AsO4 a.
