Thinking About Acid–Base Problems• What are the major species in solution?• What is the dominant reaction that will take place? Is it an equilibrium reaction (弱酸/鹼) or a reaction that will go essentially to completion React all major species until you are left with an equilibrium reaction.• Solve for the pH if needed.Example: (a.) Calculate the pH of 1.0 M solution of HCl(b.) Calculate the pH of 1.0x10-10 M solution of HCl*The major species in the solution dominate the pH(a.) The major species: H+, Cl-, H2O* H+ from dissociation of H2O
