4. Based on the amount of water you used during the
recrystallizalion (35 ml of water used),
estimate the amount of salicylic acid that was lost as a result of
being
dissolved in the filtrate. Assume that the recrystallization
solution was
cooled to 10°C; the solubility of salicylic acid at that
temperature is
0.14 g per 100 mL of water.
5. Describe and explain the possible effect on your results of the
follow-
ing experimental errors or variations. (a) You added only enough 3
M
H,SO, to bring the pH down to 4. (b) Your reaction mixture had an
oily
layer on top when you added the 3 M sulfuric acid. (c) Because of
a
label-reading error by a lab assistant, the bottle labeled
"salicylic acid
from benzene" actually contained acetylsalicylic acid
(aspirin).
