Solving Titration Problems-53
Each type of problem will require a different strategy.Write down the balanced chemical equation for the reaction between the acid and the base (this will typically be given to you in the problem as well).

Titrations are hardly ever performed with a combination of a weak acid and a weak base, because it would be more difficult to find the equivalence point for this kind of titration.

Write down what you know and figure out what the problem is asking for.

For a strong acid paired with a strong base, the p H at equivalence is 7.

For a strong acid titrant and weak base analyte, take the number of moles of weak base originally present and divide by the new total volume (original volume of analyte volume of titrant added to reach equivalence) to find concentration, then take the negative log of this concentration.

If the solute is a base, the titrant will be an acid and vice versa.

Hydrochloric acid, nitric acid, sulfuric acid, perchloric acid, hydrobromic acid and hydroiodic acid are the common strong acids, while lithium, sodium, potassium, rubidium, calcium, strontium and barium hydroxides are strong bases.

First the student pipetted 25.00 m L of the cloudy ammonia solution into a 250.0 m L conical flask. A student was asked to determine the concentration of ammonia, a volatile substance, in a commercially available cloudy ammonia solution used for cleaning.2) If the analyte is a strong base and the titrant is a strong acid, the steps you follow are the same as in (1) except that the negative log of the analyte concentration will give you the p OH instead of p H. 3) If the analyte is a weak acid and the titrant is a strong base, use the Henderson-Hasselbalch equation, p H = p Ka log ( [conjugate base concentration] / remaining weak acid concentration ).The amount of conjugate base is equal to the amount of titrant you've added so far; divide it by total volume to find concentration.
