WebDec 2, 2024 · By convention, we use the pH scale to denote hydrogen ion concentrations: Equation 1b follows from 1a. If this fact is not apparent to you, please consider brushing up on logarithms; it will save you a lot of trouble in the long run! pH = – log 10 [H +] [Equation 2-1a] You must know this equation! or conversely, [H + ] = 10 –pH [Equation 2-1b] WebExample. Thus, the pH of an acidic solution of HNO 3 (10 –3 M) = 3, a basic solution of KOH having [OH –] =10 –4 M and [H 3 O +] =10 –10 M will have a pH = 10. pH of acids is generally less than 7 whereas for bases it is greater than 7. At 298 K, ionic product of water, K w can be given as:. K w = [H 3 O +] [OH –] = 10 –14. Taking the negative logarithm of …

WebThe actual value of the equivalence point (the pH at least) depends on the identity of the analyte and the titrant, so it’ll depend on the actual titration reaction. But the equivalence point occurs when the moles of an acid equal and neutralize the moles of a base.
