Briefly explain the possible effect of the following experimental errors. TLC plate procedure with drug concentration. 1. You used a 1:200 ratio of ethyl acetate/acetic acid rather than 200:1: (Note: ethyl acetate is significantly less polar than acetic acid) 2. You allowed the TLC plate to develop too long (past the point where the solvent reaches the top of the plate). 3. You used a plastic pipet rather than a thin glass spotter. 4. You labeled your plate using a pen rather than a pencil:
