chemistry module 1, acid-base titrations

what can titrations be used for?

finding conc, identifying chemicals and finding purity

what is the tolerance for a 100 cm³ and 250 cm³ volumetric flask?

100 = +- 0.2 cm³ 250 = +- 0.3 cm³

what is the tolerance for 10,25 cm³ pipette and a 50 cm³ burette?

10 = +-0.04 25= +- 0,06 50=+-0.1

how do you do a mean tire?

repeat the tire till results are 0.1 cm³ of each other then calculate mean

what do you need to do titration calculations?

con and volume of one solution and volume of one

what is the method for titration calculations?

1) work out moles

2) work out moles of other from balanced equation

3)work out conc of unknown
