Chapter 19

a proceedure in which two solutions (each with a measured volume) are combined; generally the concentration of one soln is known and the other is what's trying to be determined

• -no equilibrium
• -reaction products (conjugate weak base/weak acid) DON'T influence the pH
• -therefore the only thing that influences the pH is the change in concentration (due to both dilution and reaction)

• -eq. ratio is needed because prior to eq. point, the acid left over after titration is WEAK
• -at the eq. point, the pH isn't neutral (7); the conjugate of the weak acid (a weak base) is present and makes the solution basic
• -
