You are given the dissociation reactions of sulfuric acid:
H₂SO4(aq) + H₂O(1)→ H3O+ (aq) + HSO4 (aq) Strong
HSO₂ (aq) + H₂O(1) H₂O¹(aq) + SO4²- (aq) K₁₂ = 0.012
In order to calculate the pH of 0.1M sulfuric acid, you will:
A) Calculate [H3O+] from the first reaction (100% ionization); second reaction is insignificant
B) Calculate [H3O+] from the second reaction
C) Take into account [H3O+] concentrations from both reactions
