titration
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
-
strong acid-strong base titration
- -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)
-
weak acid-strong base (wasb)
- -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
