The percentage of uncertainty evaluates my data by showing how accurate my results are. The Sarsons and Pickling vinegar I titrated were extremely accurate as there was 0.04% and 0.05%of uncertainty, whereas the ASDA vinegar I titrated was 0.20% uncertainty; this was the highest percentage of uncertainty which shows that this vinegar is the most unreliable in order to compare to the results of the market stall vinegar titration. Conclusion:
In conclusion trading standards believe that the market stall suspect vinegar has been watered down. The concentrations present this as the standard vinegars show a similar concentration; Sarsons has the molarity of 0.88 mol dm-3, which is 5.3% in percentage concentration; ASDA has the molarity of 0.81
