Were your isolated compounds pure based on TLC? If not, with what were they contaminated?
I'm not sure what exactly it's asking me as far as what they were contaminated with. Also, the Rf values for TLC for standard and isolated were as follows:
Standard Isolated
aspirin: 3.6 cm/5.6 cm= 0.643 cm aspirin: 3.3 cm/5.6 cm= 0.589 cm
acetaminophen: 2.2 cm/5.6 cm= 0.393 cm aceta.: 0.8 cm/5.6 cm= 0.143 cm
caffeine: 1.0 cm/5.6 cm= 0.179 cm caffeine: 2.2/5.6= 0.393 cm
