Procedure for an acid alkali titration

In chemistry OCR salters b they may ask you to recall and explain the procedure for carrying out an acid-alkali titration, and be able to work out for the results.

Important terms

Stiochiometric ratio-The end point of a chemical reaction, where the mole ratio ratio is balanced.

Concentration-The amount of moles dissolved in 1dm3 of solution (units are mol dm-3)

Titrations are used to find the concentration of an acid or an alkali solution.

Standard solution-A solution where by the concentration is accurately known

The equipment

   (     Pipette-measures one volume of solution.

Burette-measure different volumes and lets you add the solution drop by drop.

1) Measure out some alkali using a pipette and put it in a flask, along with some indicator.

2) Add the acid to the alkali using a burette-giving the flask a regukar swirl to get to the end point.


4 of 6


First do a trial titration then do an accurate titration, running the acid 2cm3 of the end point then add the acid dropwise.

Overshoot happens when it has been ran past the end point.

Use Number of moles=(cxv)/1000 to calculate molarity of the unknown solution

C stands for concentration and V stands for Volume. To find the number of moles in a solution you multiply the concentration and the volume!! :)) x

yeah, if you remember that and the fact their at stiochimetric ratio you'll be fine :) good luck!
