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
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.
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
