In this experiment the initial mass of the sodium carbonate used was 2.69g. In each titration, 3 drops of methyl orange was added to the sodium carbonate solution. With this information the titration can begin, and the results obtained are shown below:

Titration readings

Titration Rough 1 2 3 4 5
Initial 0.00 4.30 22.00 21.00 15.00 25.90
Final 4.30 22.00 38.60 37.60 32.60 42.20
Titre (cm3) 4.30 17.70 16.60 16.60 17.60 16.30

Therefore, the average titre would be calculated as follows; all the titre measurements added together (not including the rough titre), and divide this amount by the total number of titrations taken. In this case, I am only going to find the average titre of 3 of the results because to have successive measurements, the titrations have to be within 0.1 of each other, and in this case it was for only 3 of the results shown above. The average titre is shown below:

16.60 + 16.60 + 16.30 = 49.50 / 3 = 16.5cm3
