The third titration of .5cm³ is an anomalous result. Therefore I would not include this result or the rough result when working out the average titration. This anomalous result may have occurred due to missing the end point of the reaction, inaccurate measurements of the pipette or burette and not noticing the final colour change accurately.

Accuracy has tried to be maintained though many procedures in the method;

Weighing using a chemical balance means that the solid's weight is correct to dp.

A graduation flask has a small percentage error and it is relatively easy to see the 50cm³ mark.

Adding the same amount of methyl orange indicator each time, and using the minimum amount of indicator needed.

Recording the burette reading to decimal places

To measure the accuracy of my results I am going to work out the percentage error for each apparatus I have used in experiment. To find this I have calculated it using the formula.

Percentage error = error x 100

Reading

The weighing of the solid was recorded to d.p. This means it has been rounded to give me this figure, e.g. if the weight recorded was .64g than the original weight could have been .65 or .645. The percentage error is then (0.005 x 100) / .64 = 0.18%

The 50cm³ graduated flask has an error of 0.cm which is 0.08% percentage error.

One drop of the burette has a volume of 0.05cm³. The results of the burette are recorded to dp. The average titration recording of the results is 1.5. Therefore the percentage error is

0.005 x 100 = 0.0%

1.5

The 5cm³ pipette has reading has an error of 0.06cm³ or a percentage error of 0.4%.

All these percentage errors are low and therefore should not badly affect the accuracy of the results. This however does not include human error which will affect the reliability and accuracy of the results. The accuracy of the results may have also been weakened due to transferring the sulphuric acid into the burette some may have spilt. This can also be a source of error for transferring the solid into the graduated flask. The other sources of human error are reading the burette reading or the pipette reading, adding too much of the sulphuric acid and not judging the colour change accurately.

These errors could lead to wrong results. The misjudgement of colour and adding too much acid solution often means that the volume of titrant used is over the actual amount needed.

These results are reliable because for each of the titrations the variables have been kept constant for each titration. The temperature will have been constant as the results were conducted in the same room within an hour of each other. The surface area of the reactant was kept the same as was the concentration as all the solution was taken from the same flask of the same solution. The pressure and light would also have remained constant as all the titrations were carried out in the same room at the same place.

The volumes used for each titration correspond to each other to 0.1cm³ of each other except the anomalous result. The results reliability increased by repeating the titration till you have accurate results also helps the reliability

The method could be improved by

· Placing a white tile underneath the conical flask to accurately judge the colour change.

· Using a wash bottle to ensure all the solid is completely transferred.

· Using a glass rod or heating the solution to ensure the solid is completely dissolved

· Using a funnel to transfer the acid solution into the burette without spilling any.

The method ensures accuracy and reliability by instructing to

· Record the exact mass of the anhydrous solid carbonate that has been measured.

· Making sure all the solid is dissolved.

· Using a pipette filler instead of just a 5cm³ beaker.

· Repeating the titration several times.

All of these may not be changed in the method, also the use of the burette and pipette as these have a low percentage error and the number of drops, which is the minimum amount needed must not be changed.
