Acid/Bases/Buffers

• pH = -log(H+)
• Ka = [H+][A-]/[HA]
• number of moles = concentration x volume
• Kw/[OH-] = [H+]
• Titration curves

  
• A strong acid and a weak base will have a low equivalence pH point, while a weak acid and a strong base will have a high equivalence point.
• pKa = -log(Ka)
