A local company sent you their green alternative for window cleaner to be tested for percent (w/v) acetic acid content. For your experiment, you first standardized your NaOH titrant with 0.8053 g of (99.80 % purity) KHP. You used 40.60 mL of NaOH for your standardization. After that you then analyzed a 10.00 mL sample and found that you needed 43.20 mL NaOH to reach the end point.

Suppose that extra volume (more than the actual volume) of 0.2 M NaOH solution was used to reach the end-point in the titration process for the determination of the % purity of aspirin sample (0.5 g). Which of the following is correct? The calculated and the actual percent purity values for the aspirin sample will be the same, since the extra added volume of NaOH solution has no effect on the % purity determination for the aspirin sample. We need to know the actual volume (the real volume that should be used in titration) as well as the used volume of NaOH solution to make a true comparison between the actual and the calculated % purity values for the aspirin sample. The calculated % purity value will be lower than the actual % purity value for the aspirin sample. The calculated % purity value will be higher than the actual % purity value for the aspirin sample.

If the same mass of Na2SO4 (MW: 142 g/mol) and K2SO4 (MW: 174 g/mol) were weighed and used for the gravimetry experiment, which will yield a greater amount of precipitate? Assume that the experiment was done correctly. • Indeterminate, it will depend on the amount of BaCl2 used. • They will yield the same amount of precipitate because the same mass was initially weighed. • K2SO4 because it has a larger molecular weight.
