Question
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 50.00 mL sample and found
that you needed 33.20 ml NaOH to reach the end point.
