titrations

Question 1

what is the effect on the titre if the volumetric flask is filled above the graduation line?

Answer 1

base becomes too dilute so a lower titre

Question 2

what is the effect on the titre if the same base is split whilst transferring to the volumetric flask?

Answer 2

fewer moles of the base so its more dilute as a result therefore a lower titre

Question 3

what is the effect on the titre if the pipette is rinsed with water before filling with the base?

Answer 3

base is diluted so lower titre

Question 4

what is the effect on the titre if the pipette is filled below the graduation line?

Answer 4

fewer moles of base so lower titre

Question 5

what is the effect on the titre if the conical flask is rinsed with water before adding the base?

Answer 5

same moles of base so same titre

Question 6

what is the effect on the titre if the conical flask is rinsed with base before adding the base

Answer 6

too much base so greater titre

Question 7

what is the effect on the titre if the burette is rinsed with water before adding the acid?

Answer 7

fewer moles of acid as its been diluted so greater titre

Question 8

what is the effect on the titre if the burette is read from the top of the meniscus each time?

Answer 8

same titre as burettes measure by difference

Question 9

what is the effect on the titre if a droplet of base remains in the tip of the pipette and can’t be removed?

Answer 9

same titre because the manufacturer takes this into account
