volumetric flask uncertainties
100cm3 volumetric flask-> +/- 0.20cm3
250cm3 volumetric flask-> +/- 0.30cm3
preparing standard solution
weigh solid accurately
solid dissolved in a beaker using less distilled water than needed to fill vf to mark
solution transferred to vf, last traces are rinsed into flask using distilled water
flask carefully filled to graduation line by adding distilled water until bottom of meniscus lines up with mark
invert vf slowly several times to mix solution thoroughly
10cm3 pipette->+/- 0.04cm3
25cm3 pipette->+/- 0.06cm3
50cm3 burette->+/- 0.10cm3
