Three students are asked to discuss the sources of error that might have affected the outcome of the lab. Select the student that employs correct scientific reasoning. Student 1: If the spot was placed below the solvent level, this would cause the sample to be dissolved into the solvent pool before traveling up the plate. Student 2: If the solvent used has the opposite polarity of the stationary phase this will cause unequal movement of the sample. Student 3: If the developing chamber was closed too quickly than the sample wouldn't be able to travel on the TLC plate.
