The student adds dilute sulfuric acid from a burette until the end-point is reached. The student carries out the titration four times. Figure 1 shows the volume of sulfuric acid used in each of the four titrations. The final burette reading in titration 1 is 24cm' The initial burette reading in titration 1 was 2cm' Volume of acid used in titration 1 was 22cm" The final burette reading in titration 2 is 46.10cm' The initial burette reading in titration 2 was 24.00cm' Volume of acid used in titration 2 was 22.10cm' The final burette reading in titration 3 is 22.70cm The initial burette reading in titration 3 was 0.00cm' Volume of acid used in titration 3 was 22.70cm' The final burette reading in titration 4 is 44.90cm The initial burette reading in titration 4 was 22.70cm Volume of acid used in titration 4 was 22.20cm' i) Two of the titrations above should not be used to calculate the mean volume of sulfuric acid used. State and explain which two titrations should not be used to calculate the mean Titration number: Reason: Titration number. Reason: ii) calculate the mean volume of sulfuric acid used to neutralise the sodium hydroxide solution. Give your answer to 2 d.p mean volume=
