Titration

Titration

Method

Same volume of acid + alkali

If both same concentration you get a neutral solution

Titration used to calculate concentration of the other reactant

1. Add know volume of alkali into conical flask usuing a pipette

2. Add a few drops of indicator - Methyl orange or Phenolphthalein

3. Pour some acid into a burette and record the reading (volume inside)

4. Open the tap, add a small amount of acid and swirl the conical lask

5. Add acid until the solution is neutral, shwon by the colour change in indicator

6. Repeat 3 times

Calculations

If the concentration of one of the reactants is unknown, the results of a titration can be used to ind the concentration of the other reactant

1decimetre cubed = 1000cm cubed = 1 litre
